A basic compiler based off of @thejameskyle's super-tiny-compiler, compiles a simple LISP-esque syntax into runnable JS.

Currently supports a few built-ins, add, subtract, assign, def and log. Hopefully these are self-explanatory, or at least they should be from example.mc. A ; denotes that the rest of the line (until the compiler sees \n) as a comment and means that it will not be compiled.

In addition to the regular include(coming soon), there is also a preprocessing directive called `source <filename> which can be used to just directly insert the contents of <filename> into the file. Instead of wasting the compilers energy checking for circular sources, you have two options, to not be so stupid or wait for the call stack to overflow.

The compiler runs like node compiler.js file.mc where file.mc is the file you wish to compile, and this will produce a file.mc.js which requires the lib to be present in the same directory when running for now at least.

Functions and variables are in different scopes, so variables can have the same names as functions - even builtins, thus making (assign assign 5) a totally okay thing to do.

Note that this compiler is not only totally useless, but also horrendously inefficient. Either way it's a fun exercise :)
