### compiler.py / compiler_beta.py
This compiler compiles from 'tronScript' to a binary save-state of the emulator. It has been designed with the main priority of being as easy as possible to compile. Usability was ~~maybe~~ impacted by this decisio.
I forgot, what the difference between normal and beta is...
compiler_beta does not work, but contains code to add stack / push / pop functionality to tronScript.
More information about tronScript can be found in TronScript_README.txt

Available Commands:
newVar [var] - Initializes new var; not needed most of the time:
newVar [name] - Initializes new var; not needed most of the time:
Compiler automatically initializes new vars when used,
so this is no longer necessary...
newArray [name] [len] - Initializes a new array with length len.
jumpMark [jumpMark name] - Sets an JumpMark to jump to using the "jump" command
jump [jumpMark name] - Jumps to an JumpMark
getVarAddress [var A] [var B] - Saves [var A]'s memory-address into [var B]

Fun Fact: Pascal used to do a similar thing, which is why you couldn't
do recursion in early versions of Pascal.
Q: There are some command ś that operate on an array. How do I initialize one?
A: Good Question. Do you know, what defines a good question? That you dont have an answer to it...
