Introducing bytecode simplifier

Bytecode simplifier is a tool to deobfuscate PjOrion protected python scripts. It is a complete rewrite of my earlier tool PjOrion Deobfuscator. I have reimplemented the deobfuscation functionality from scratch and have used networkx specifically for this purpose. Using networkx made reasoning about the code much simpler.
The PjOrion version used is 1.3.2 (Filename: PjOrion_Uncompyle6_01.10.2016.zip)

The code is at https://github.com/extremecoders-re/bytecode_simplifier
