Encoders in C++

[breznak]

In order for nupic.core to be stand-alone we'll need to reimplement most of encoders from nupic/python to c++.

My motivation for this are large-scale experiments, where python is eating huge amounts of memory.

For starters I suggest base.py and scalar encoder

Related to https://github.com/numenta/nupic.core/issues/7.

• [x] Create base Encoder class
• [ ] Create C++ date/time encoder
• [ ] Create C++ scalar encoder
• [ ] Create C++ category encoder

Related to work defined in the extraction plan. We need to have a discussion on nupic-hackers about which encoders should be translated.

base, RDSE/Scalar & Date seem to be the important for starters.

I don't really consider this an optimization...
