// SYNOPSIS
//
template< class T > class auto_vec
//
// DESCRIPTION
//
// A auto_vec<T> will delete the vector of objects it points to upon
// destruction. This is very similar to STL's auto_ptr<T>, but for
// vectors.
//
// SEE ALSO
//
// Bjarne Stroustrup. "The C++ Programming Language, 3rd ed."
// Addison-Wesley, Reading, MA, 1997. pp. 367-368.
