Local examples

• Basic program to compute sum of squares from 1 to 4
• Same program, but correct...
  Here, we first save some IMPORTANT registers on the stack (such as the address from where we were called),
  and so, after doing whatsoever, we can jump back to that address.
• Another variation of the same stuff.
  Here we use the memory commands "load-word" & "store-word" to save some data, instead in registers.
• Last variation, here we ask for an integer (n),
  and compute sum of squars from 1 to n
