Replaced deprecated compiler module usage with the ast module

The compiler module was deprecated back in Python 2.6 (source: https://docs.python.org/2.7/library/compiler.html), so I've replaced it's usage with funcionality from the now preferred ast module (https://docs.python.org/2.7/library/ast.html).
