The stack is probably the most basic storage structure, using the 'first-in, first-out' approach. The following functions are the only ones available for stack manipulation, as it is quite a minimalistic data structure. The STACK_TYPE is a constant defined above the stack functions which can be set by the user to determine the type of items in the stack. By default it is left as an integer.
