Builder Code Calling For ASTs

So we have our AST, and we have a builder API. Put them together, and now any generated AST can be converted into a program we can compile and run. But how exactly does this process work? ANTLR4 does not just give us an AST, but it gives us a way of reading it to!

ANTLR Visitors

Current visitor code is out of date and does not use the new builder API yet. See here for AST visiting code.
