/*****************************************************************************
 Demo for the template class 'V' as an interface to 'Vec' and 'sumVec'

 The program asks the user for a sequence of Vec's or sumVec's. It stores them 
 in a vector, then displays them.

 Note the simplified access to dynamic binding provided by 'V'.
