The circom compiler

This repository uses a modified version of the circom compiler found at alex-ozdemir/circom. It includes a few extra features not found in the original:

• Clearer error printouts
• More comprehensive/informative treatment of log statements
• A new type int which enables bigints to be handled during witness computations.
• compute blocks
