        Takes a sub-section of an HTML Vector and removes all TextNode present
        Parameters:
        page - Any HTML page
        sPos - This is the (integer) Vector-index that sets a limit for the left-most Vector-position to inspect/search inside the input Vector-parameter.

        This value is considered 'inclusive' meaning that the HTMLNode at this Vector-index will be visited by this method.

        NOTE: If this value is negative, or larger than the length of the input-Vector, an exception will be thrown.
        ePos - This is the (integer) Vector-index that sets a limit for the right-most Vector-position to inspect/search inside the input Vector-parameter.

        This value is considered 'exclusive' meaning that the 'HTMLNode' at this Vector-index will not be visited by this method.

        NOTE: If this value is larger than the size of input the Vector-parameter, an exception will throw.

        ALSO: Passing a negative value to this parameter, 'ePos', will cause its value to be reset to the size of the input Vector-parameter.
        Returns:
        The number of HTML TextNode's that were removed
        Throws:
        java.lang.IndexOutOfBoundsException - This exception shall be thrown if any of the following are true:

        • If 'sPos' is negative, or if sPos is greater-than-or-equal-to the size of the Vector
        • If 'ePos' is zero, or greater than the size of the Vector
        • If the value of 'sPos' is a larger integer than 'ePos'. If 'ePos' was negative, it is first reset to Vector.size(), before this check is done.

                               int ePos)
        This method removes all inner-tags (all attributes) from every TagNode inside of an HTML page. It does this by replacing every TagNode in the Vector with the pre-instantiated, publicly-available TagNode which can be obtained by a call to the class HTMLTags.hasTag(token, TC).

        Replacing TagNode's:
        This method determines whether a fresh TagNode is to be inserted by measuring the length of the internal HTMLNode.str field (a String field). If the length TagNode.str is not equal to the HTML token TagNode.tok length plus 2, then a fresh, pre-instantiated, node is replaced.

        The '+2' figure comes from the additional characters '<' and '>' that start and end every HTML TagNode
        Parameters:
        html - This may be any Vectorized-HTML Web-Page (or sub-page).

        The Variable-Type Wild-Card Expression '? extends HTMLNode' means that a Vector<TagNode>, Vector<TextNode> or Vector<CommentNode> will all be accepted by this paramter without causing an exception throw.

        These 'sub-type' Vectors are often returned as search results from the classes in the 'NodeSearch'vpackage.
        sPos - This is the (integer) Vector-index that sets a limit for the left-most Vector-position to inspect/search inside the input Vector-parameter.

        This value is considered 'inclusive' meaning that the HTMLNode at this Vector-index will be visited by this method.

        NOTE: If this value is negative, or larger than the length of the input-Vector, an exception will be thrown.
        ePos - This is the (integer) Vector-index that sets a limit for the right-most Vector-position to inspect/search inside the input Vector-parameter.

        This value is considered 'exclusive' meaning that the 'HTMLNode' at this Vector-index will not be visited by this method.

        NOTE: If this value is larger than the size of input the Vector-parameter, an exception will throw.

        ALSO: Passing a negative value to this parameter, 'ePos', will cause its value to be reset to the size of the input Vector-parameter.
        Returns:
        The number of TagNode elements that have were replaced with zero-attribute HTML Element Tags.
        Throws:
        java.lang.IndexOutOfBoundsException - This exception shall be thrown if any of the following are true:

        • If 'sPos' is negative, or if sPos is greater-than-or-equal-to the size of the Vector
        • If 'ePos' is zero, or greater than the size of the Vector
        • If the value of 'sPos' is a larger integer than 'ePos'. If 'ePos' was negative, it is first reset to Vector.size(), before this check is done.

        This method does the same thing as nodes(boolean, Vector, int[]), but all error checking is skipped, and the input integer array is presumed to have been sorted. There are no guarantees about the behavior of this method if the input array 'posArr' is not sorted, least-to-greatest, or if there are duplicate or negative values in this array.

        Empty Var-Args:
        If the var-args input integer-array parameter is empty, this method shall exit gracefully (and immediately).
        Parameters:
        page - Any HTML-Page, usually ones generated by HTMLPage.getPageTokens, but these may be obtained or created in any fashion so necessary.
        posArr - An array of integers which list/identify the nodes in the page to be removed. Because this implementation has been optimized, no error checking will be performed on this input. It is presumed to be sorted, least-to-greatest, and that all values in the array are valid-indices into the vectorized-html parameter 'page'

        Parameters:
        preserveInputArray - This is a convenience input parameter that allows a programmer to "preserve" the original input-parameter integer-array that is passed to this method. It could be argued this parameter is "superfluous" - however, keep in mind that the passed parameter 'nodeList' must be sorted before this method is able function properly. There is a sort that's performed within the body of this method. Just in case that the original order of the integer-array input-parameter must be preserved, its possible to request for the sort to operate on "a clone" of the input-parameter integer-array, instead of the original integer-array 'nodeList' itself.
        page - Any HTML-Page, usually ones generated by HTMLPage.getPageTokens(...), but these may be obtained or created in any fashion so necessary.
        nodeList - An array of integers which list/identify the nodes in the page to be removed.
        Throws:

        This will do an "Inclusive Search" using the standard class TagNodeInclusiveIterator in the package NodeSearch. Then it will inspect the contents of the subsections. Any subsections that do not contain any instances of HTMLNode in between them, or any subsections that only contain "blank-text" (white-space) between them shall be removed.

        Recursive Method:
        The search logic shall perform multiple recursive iterations of itself, such that if, for instance, the user requested that all empty HTML divider (<DIV>) elements be removed, if after removing a set a dividers resulted in more empty ones (nested <DIV> elements), then an additional removal shall be called. This recursion shall continue until there are no empty HTML elements of the types listed by 'htmlTags'
        Parameters:
        page - Any vectorized-html page or sub-page.
        sPos - This is the (integer) Vector-index that sets a limit for the left-most Vector-position to inspect/search inside the input Vector-parameter.

        This value is considered 'inclusive' meaning that the HTMLNode at this Vector-index will be visited by this method.

        NOTE: If this value is negative, or larger than the length of the input-Vector, an exception will be thrown.
        ePos - This is the (integer) Vector-index that sets a limit for the right-most Vector-position to inspect/search inside the input Vector-parameter.

        This value is considered 'exclusive' meaning that the 'HTMLNode' at this Vector-index will not be visited by this method.

        NOTE: If this value is larger than the size of input the Vector-parameter, an exception will throw.

        ALSO: Passing a negative value to this parameter, 'ePos', will cause its value to be reset to the size of the input Vector-parameter.
        htmlTags - The list of inclusive (non-singleton) html elements to search for possibly being empty container tags.
        Returns:
        The number of HTMLNode's that were removed.
        Throws:
        java.lang.IndexOutOfBoundsException - This exception shall be thrown if any of the following are true:

        • If 'sPos' is negative, or if sPos is greater-than-or-equal-to the size of the Vector
        • If 'ePos' is zero, or greater than the size of the Vector
        • If the value of 'sPos' is a larger integer than 'ePos'. If 'ePos' was negative, it is first reset to Vector.size(), before this check is done.
        Code:
        Exact Method Body:
         DotPair subList;

 int             removed = 0;
 HNLIInclusive   iter    = TagNodeInclusiveIterator.iter(page, htmlTags);
 LV              l       = new LV(page, sPos, ePos);

 iter.restrictCursor(l);

 TOP:
 while (iter.hasNext())

     // If there is only the opening & closing pair, with nothing in between,
     // then the pair must be removed because it is "Empty" (Inclusive Empty)

     if ((subList = iter.nextDotPair()).size() == 2)
     {
         iter.remove();
         ePos -= subList.size();
         removed += subList.size();
     }

     else
     {
         // If there is any TagNode in between the start-end pair, then this is NOT
         // EMPTY.  In this case, skip to the next start-end opening-closing pair.

         for (int i=(subList.start + 1); i < subList.end; i++)
             if (! page.elementAt(i).isTextNode())
                 continue TOP;

         // If there were only TextNode's between an opening-closing TagNode Pair....
         // **AND** those TextNode's are only white-space, then this also considered
         // Inclusively Empty.  (Get all TextNode's, and if .trim() reduces the length()
         // to zero, then it was only white-space.

         if (Util.textNodesString(page, subList).trim().length() == 0)
         {
             iter.remove();
             ePos -= subList.size();
             removed += subList.size();
         }
     }

 // This process must be continued recursively, because if any inner, for instance,
 // <DIV> ... </DIV> was removed, then the outer list must be re-checked...

 if (removed > 0)
     return removed + Remove.inclusiveEmpty(page, sPos, ePos, htmlTags);

        public static void firstLast​(java.util.Vector<? extends HTMLNode> html)
        Removes the first and last element of a vectorized-HTML web-page, or sub-page. Generally, this could be used to remove the surrounding tag's '<DIV>' ... '</DIV>', or something similar.

        This method WILL NOT CHECK whether there are matching HTML open-and-close tags at the end beginning and end of this sub-section. Generally, though, that is how this method is intended to be used.
        Parameters:
        html - This may be any Vectorized-HTML Web-Page (or sub-page).

        The Variable-Type Wild-Card Expression '? extends HTMLNode' means that a Vector<TagNode>, Vector<TextNode> or Vector<CommentNode> will all be accepted by this paramter without causing an exception throw.

        These 'sub-type' Vectors are often returned as search results from the classes in the 'NodeSearch'vpackage.
        Throws:
        java.lang.IllegalArgumentException - If the Vector has fewer than two elements.
        Code:
        Exact Method Body:
         int size = html.size();

 if (size < 2) throw new IllegalArgumentException(
     "You have requested that the first and last elements the input 'page' parameter " +
     "(a vector) be removed.  However, the vector size is only [" + size  + "], so " +
     "this cannot be performed."
 );

 // NOTE: *** This removes elementAt(0) and elementAt(size-1)
 //       *** NOT ALL ELEMENTS BETWEEN 0 and (size-1)

 Util.Remove.nodesOPT(html, 0, size-1);
