edit 1/13/2016: MG sigs + demo are done (git clone https://github.com/ShenNoether/MiniNero.git, cd brief, make, a.exe (or a.out depending on system)). Most of the helper functions are there, so the rest should go a little bit quicker. Also fixed a tiny bug in Monero's keccak function.
edit 1/15/2016: spent an all nighter getting a rough version of all the code finished - I will most likely clean it up, and then make it available early next week.
