* #10 CGP Circuits as inputs (#11) * CGP Circuits as inputs * #10 support of signed output in general circuit * input as output works * output connected to input (c) * automated verilog testing * output rename * Implemented CSA and Wallace tree multiplier composing of CSAs. Also did some code cleanup. * Typos fix and code cleanup. * Added new (approximate) multiplier architectures and did some minor changes regarding sign extension for c output formats. * Updated automated testing scripts. * Small bugfix in python code generation (I initially thought this line is useless). * Updated generated circuits folder.
