This commit intent to complete two things

1 : improve the speed of SparseAutoencoder
I cache the computation result in the data member, so the algorithm do not need to compute it two times.Since the member function is const, I declared the data member as mutable;Do anyone think that make the member function as non-const would be better?

2 : make the SparseAutoencoder more versatile
I add two template parameters as following

template<typename HiddenLayer, typename OutputLayer>
class SparseAutoencoderFunction;

This allow users use different layer from ann two compute the features
