Restructure class methods into individual files

[mateogianolio]

Features

• Improved maintainability by breaking out all class methods into separate files. Intended side-effects of this is that we will be more prepared for
  1. WASM compilation with AssemblyScript (Investigate WebAssembly integration #102)
  2. Accelerating some or all of the class methods in C++
  3. Providing a framework for writing additional extensions mentioned in Machine learning #45, Mathematical statistics #55, Random sampling #145, Discrete fourier transform #146, Complex numbers #149, Computational physics #150
  • Restructure NDArray
  • Restructure Vector
  • Restructure Matrix
• Improved typings by using TypeScript generics.
• Improved test suite by having one spec file per function instead of having one spec file per class.
• Improved benchmarks by having one benchmark file per function.
• NDArray
  • Add reshape, slice, equidimensional, equilateral methods.
• Matrix
  • Add eig method that returns eigenvalues and eigenvectors.
  • Add nlapack dependency and accelerate matrix methods eig, inv, lu, lu_factor, solve.

Breaking changes

• NDArray
  • Switch to dtype: DType instead of type: TypedArrayConstructor.
  • Remove min and max arguments from random method.
• Matrix
  • Rename plu to lu_factor.
  • Rename determinant to det.
  • Rename inverse to inv.
  • Rename identity to eye and move it to NDArray.
• Vector
  • Rename magnitude to norm and move it to NDArray.
