Better Documentation and/or Examples

[joaopauloschuler]

The documentation should include:

• Fitting options (Image classification, volume pairs, callbacks).
• Layer activation functions.
• How to hide or override warnings and errors when optimizing a NN.
• Include an autoencoder example and describe the importance of Hyperbolic Tangent with autoencoders and generative networks.

I saw the recent commits with new layer types (like addConcatInputOutput).
The description of what does these layer types would be appreciated.
I also noted some layers types are not described (or listed) in the documentation, like the dropout layer.
Can you update a give a short description of what it does for each layer type.
Thanks

Thank you for the heads up. I'll work on it.
