Change how the Coordinates Transform! - Again!

🐞 Problem

Current state of the coordinates make everything too slow. I want speed. And I am gonna make things too fast! xD

No @ritzvik The goals are different!

@rishi-s8 , this is a classical computation problem, where you might one day have multiple coordinate reference frames, so you will need to write a function in every other class to change to the new class.

Instead, what I feel is we should have something like a coordinate transformation graph! See this: http://docs.astropy.org/en/stable/api/astropy.coordinates.TransformGraph.html

We mostly require Cartesian, Spherical Polar, Boyer-Lindquist and Kerr-Schild Coordinates and a transformation among them. For most of numerical relativity, these are sufficient. “Exotic” coordinates can be added, as and when needed. Also, only “Kerr-Schild” is missing at the moment.
