Neural Network Toolbox based on TensorFlow

In development. No document, don't use.

• Scoped abstraction of common models.
• Provide callbacks to control training behavior (as in Keras).
• Use Dataflow to gain fine-grained control on data preprocessing.
• Automatically use the Queue operator in tensorflow to speed up input.
• Training and testing graph are modeled together. Just need to follow the conventions to setup stuffs.
• Use tensorboard easily.
