Have been reading a great book on neural network by Tariq Rashid. Took the lessons from his book and created a basic neural network that recognizes handwritten numbers. Used this as an opportunity to opportunity the create a matrix math library and optimize the JIT compilers for float point functions.

Optimizations and speed increases.

Highlights:
1. JIT support for floating point functions (pow, sin, cos, log, etc.) [new]
2. More aggressive method inlining, general increased performance [new]
3. Fixed code examples [bug]
