Simple Bezier Curve Library

This is more of like a practice. I am rewriting essentially the same thing as bezier-js by following the Superb Guide on Bezier Curve by Pomax, with my own interpetation and I/O. This is to be used on one of my future projects invloving a simulation of rail system and I plan on doing it with bezier curves. This is also the first time that I am incorporating TDD into my development flow. I am trying to start small and take baby steps, hopefully I can apply TDD on something that has a greater scope than this project does. This project is still early on I only implemented some of the features, but feel free to take a look at it. I plan to release the package on npm as well.
