Create Python Wrapper for Atlas CoSim

See the Sparta repo for some inspiration: https://github.com/sparcians/map/tree/e736f0dabaa6ee4704ada11f63d6b36028c5d532/sparta/python/sparta_support

Create a Python wrapper for the CoSim API to be able to run Atlas in IPython. The end goal would be to be able to use IPython like a debugger for investigating functional bugs. Once we implement flushing in cosim, we will be able to implement "step" and "step back" commands to move simulation forwards and backwards.
