Stack working

The Calculation will now run, and then jump ahead of the stack.
Prints out the Stack

Currently prints out the stack, but needs code to jump forward after
stack is finished
Before Bed

Calculate 2^n needs a bugfix where it's not running through the full
current stack each time it recalculates.

I am trying to track where the head and tail of the stack are, and break
the loop if they are equal and the head = 0
