Itcl_InitStack initializes a stack structure and Itcl_DeleteStack deletes it. Itcl_PushStack pushes the cdata value onto the stack. Itcl_PopStack removes and returns the top most cdata value. Itcl_PeekStack returns the top most value, but does not remove it. Itcl_GetStackValue gets a value at some index within the stack. Index "0" is the first value pushed onto the stack. Itcl_GetStackSize returns the count of entries on the stack.
