// The CoolStack class is  publicly  derived from the  Generic class and is used to
// implement non-type specific functionality for the parameterized CoolStack class.
// In  this manner, code common  to  all instances  of the  CoolStack  class can be
// shared to reduce code replication.  The  CoolStack class  implements a one
// dimensional vector of a user-specified type.  This  is accomplished by using
// the parameterized type  capability of C++.  The  stack will grow dynamically
// as necessary  with   the amount  of  growth determined  by  the value  of an
// allocation size slot.  Fixed length stacks are also supported by setting the
// value of the allocation size slot to zero.
