Adaptive visualization module: implement neural network classifier

[bmzernichow]

• Use Tensorflow high-level machine learning API tf.contrib.learn to build a neural network (I.e. Multilayer Perceptron - MLP)
• The MLP will train a classifier for visualization charts
• Use classifier as part of recommender system in visualization module
