Detailed Description

This class is the actual engime implementation. It is kept separate from the engine class to allow editing without having to recompile large portions of the program. It also makes interfacing safer as one has limited access to the internals of the engine.

In the future, there may be different types of engine (MPI-based engines, pure learning engines, etc) and this will make it much easier to implement and work on those w/o exposing the logic to the rest of the program. I do need to move some of the engineimp functions to the engine class, however. But for now, I need to get the c-elegans code running and some proper tutorials written
