    [FLINK-3742] Add Multilayer Perceptron 

    https://en.wikipedia.org/wiki/Multilayer_perceptron
    
    Multilayer perceptron is a simple sort of artificial neural network. It creates a directed graph in which the edges are parameter weights and nodes are non-linear activation functions. It is solved via a method known as back propagation.
    
    I anticipate this being an ongoing thing for a bit. I'll be working on docs in the meantime and commit soon.
    
    A note on the tests. Neural-nets take a while to fit by their nature. I recommend using the warm starts and verifying that it is getting closer after a few batches of iterations, and some other tests for the unit functionality (winding/unwinding parameter matrix arrays, etc.)
