 * void process()
 *
 * Process the current command.  For dynamic stack-as-arrays, these include:
 *
 *  Constructors
 *
 *   new             constructor     create a stack with the default array size
 *   new: n          constructor     create a stack with an array size of n
 *
 *  Accessors
 *
 *   size n          size            the size equals n
 *   capacity n      capacity        the capcity equals n
 *   empty b         empty           the result is the Boolean value b
 *   top n           top             n is the top element in the stack
 *   top!            top             the underflow exception is thrown
 *   max n           maximum         n is the maximum element in the stack
 *   max!            maximum         the underflow exception is thrown
 *   min n           minimum         n is the minimum element in the stack
 *   min!            minimum         the underflow exception is thrown
 *
 *  Mutators
 *
 *   push n          push            the element can be push (always succeeds)
 *   pop n           pop             the top can be popped and returns n
 *   pop!            pop             the underflow exception is thrown
 *   clear           clear           clears the stack
 *
 *  Others
 *
 *   cout            cout << stack   print the stack (for testing only)
 *   summary                         prints the amount of memory allocated
 *                                   minus the memory deallocated
 *   details                         prints a detailed description of which
 *                                   memory was allocated with details
 *   !!                              use the previous command, e.g.  5 push_front 3
 *                                                                   6 !! 7         // same as push_front 7
 *   !n                              use the command used in line n  7 front 7
 *                                                                   8 !7 9         // same as push_front 9
