File:Stack
Purpose:A stack is a last-in-first-out collection.

Notes:* Non-char primitive values will have their own IntegerStack() say,that calls PrimitivePush and
converts to/from character to their native datatype.
is dynamically constructed, but stacks need to be lightweight at runtime (IMO anyway).
