     Class RRRRWWWWGGGGVVVVeeeeccccttttoooorrrr((((vvvvaaaallll)))) represents a group of ordered elements, accessible
     by an index.  Duplicates are allowed. This class is implemented as an
     array.  Objects of type RRRRWWWWGGGGVVVVeeeeccccttttoooorrrr((((vvvvaaaallll)))) are declared with macros defined
     in the standard C++ header file <<<<ggggeeeennnneeeerrrriiiicccc....hhhh>>>>. Note that it is a vvvvaaaalllluuuueeee----
     bbbbaaaasssseeeedddd collection: items are copied in and out of the collection.  The
     class vvvvaaaallll must have:
          a default constructor;

          well-defined copy semantics (vvvvaaaallll::::::::vvvvaaaallll((((ccccoooonnnnsssstttt vvvvaaaallll&&&&)))) or equiv.);

          well-defined assignment semantics (vvvvaaaallll::::::::ooooppppeeeerrrraaaattttoooorrrr====((((ccccoooonnnnsssstttt vvvvaaaallll&&&&)))) or
          equivalent).


PPPPeeeerrrrssssiiiisssstttteeeennnncccceeee
     For each type of RRRRWWWWGGGGVVVVeeeeccccttttoooorrrr, you must include one (and only one) call to
     the macro iiiimmmmpppplllleeeemmmmeeeennnntttt, somewhere in your code.  None

              RRRRWWWWGGGGVVVVeeeeccccttttoooorrrr((((vvvvaaaallll))))();


     Construct an empty vector.

              RRRRWWWWGGGGVVVVeeeeccccttttoooorrrr((((vvvvaaaallll))))(size_t n);


     Construct a vector with length nnnn. The initial values of the elements can
     (and probably will) be garbage.

              RRRRWWWWGGGGVVVVeeeeccccttttoooorrrr((((vvvvaaaallll))))(size_t n, vvvvaaaallll v);


     Construct a vector with length nnnn. Each element is assigned the value vvvv.

              RRRRWWWWGGGGVVVVeeeeccccttttoooorrrr((((vvvvaaaallll))))(RWGVector(vvvvaaaallll)& s);


     Copy constructor.  The entire vector is copied, including all embedded
     values.

     Assignment operator.  The entire vector is copied.

              RWGVector(vvvvaaaallll)&
          ooooppppeeeerrrraaaattttoooorrrr====(vvvvaaaallll v);


     Sets all elements of self to the value vvvv.

     Return the iiii'th element in the vector.  The index iiii must be between zero
     and the length of the vector less one.  No bounds checking is performed.
     The second variant can be used as an lvalue.

     Return the iiiith element in the vector.  The index iiii must be between zero
     and the length of the vector less one.  Bounds checking is performed.

     Resize the vector.  If the vector shrinks, it will be truncated.  If the
     vector grows, then the value of the additional elements will be
     undefined.
