 The first step in this project included writing classes for each Bril instruction. For code reuse, we organized these classes in a hierarchy that would 
 allow for similarities in instructions to be in common classes using inheritance. The main idea for this is if we needed to tweak these common aspects in 
 the instruction classes, the change would be in one place rather than having to keep track of all the different files to update. The other reason why we dealt 
-with objects rather than bril text or bril JSON, was because it is easier to keep track and update operands in an object format.

 This was implemented as a dictionary in Python. So, if we come across a variable that is already in this dictionary, this means that we have seen it before and had already assigned it

 The next step is to actually perform the trivial register allocation for each instruction in our function. As described above, this involves adding additional instructions before and after each instruction to load the appropriate temps off the stack, perform the operation, and then store the temps back onto the stack. The important property of when to add instructions before or after an instruction X is the following:
