For each type of RWGOrderedVector you must include one (and only one) call
to the macro implement somewhere in your code for both the
RWGOrderedVector itself and for its base class RWGVector .
Example Here's an example that uses an ordered vector of RWCStrings .
Program output:
First
Second
Last
Public constructors RWGOrderedVector( val )(size_t capac=RWDEFAULT_CAPACITY);
Construct an ordered vector of elements of type val. The initial capacity of the
vector will be capac whose default value is RWDEFAULT_CAPACITY . The
capacity will be automatically increased as necessary should too many items be
inserted, a relatively expensive process because each item must be copied into
the new storage.

vec.insert(one);
