This PR updates some of the internal structure of the library. Most importantly
array_2d.cppnow contains code only related to the rubyArray2Dclass, and all the lower level, mostly ruby-independent C++ statistics code has moved todfloat.cpp.In addition, this adds support for compiling the gem without SIMD intrinsics at all using
FAST_STATISTICS_DISABLE_SIMD=1 gem install fast_statistics. This allows testing the behaviour in an environment wherexmmintrinis not available, and also allows manually disabling SIMD if desired. The travis CI config runs the test suite with and without SIMD.
