003/**
004 * This simple generic-class allows a function to return <B STYLE='color:red'>seven</B> objects as
005 * a result, instead of just one.   This is not always so useful, and can make code confusing.
006 * However there are some instances where the only alternative would be to create an entirely new
007 * class/object, when only a single method result would use that object.
008 *
009 * <BR /><BR /><B CLASS=JDDescLabel>Field Name Change:</B>
010 * 
011 * <BR />For the classes {@link Ret6}, {@code Ret7} &amp; {@link Ret8} - the field names include a
012 * number as well (see {@link #a1}, {@link #b2}, {@link #c3} etc...).  This is simply due to the
013 * fact that these Field-Names become progressively more difficult to read or even look at after
014 * the first four or five letters - {@code 'a', 'b', 'c', 'd'} and {@code 'e'}.
015 * 
016 * <EMBED CLASS=globalDefs DATA-KIND=Ret DATA-N=7>

018 * @param <A1> The type of the <B STYLE='color:red'>first</B> member-field ('{@link #a1}').
019 * @param <B2> The type of the <B STYLE='color:red'>second</B> member-field ('{@link #b2}').
020 * @param <C3> The type of the <B STYLE='color:red'>third</B> member-field ('{@link #c3}').
021 * @param <D4> The type of the <B STYLE='color:red'>fourth</B> member-field ('{@link #d4}').
022 * @param <E5> The type of the <B STYLE='color:red'>fifth</B> member-field ('{@link #e5}').
023 * @param <F6> The type of the <B STYLE='color:red'>sixth</B> member-field ('{@link #f6}').
024 * @param <G7> The type of the <B STYLE='color:red'>last</B> member-field ('{@link #g7}').
