adding documentation to Model items
added more documentation and tests
corrected enumerable proeprty serialization bug. Added Descriptior serialization tests
beggining neural network implementation
beggining infrastructure for neural nets
structure for neural nets complete, still implementing backprop
completed neural network algorithm (needs checking)
rehashing of nn algorithm
corrected various NN computations
made additional NN corrections, added test to run generator 1000 times for better results
changes to support network visualization
changed comments to reflect truth, NN's seem to be working properly
corrected KNN index error and strngthened overall model testing on the supervised side
merging dev branch - added neural nets as big feature
