Migrate repo to Python 3

[capsulecorplab]

I've been considering this migration for a while. This migration would entail a complete purge of the contents of this repo, following a rewrite of the trajectory simulations in Python 3. Reasons for this migration include, but not limited to:

• Exploring the Hyperloop design as a testbed for practicing model-based systems engineering (MBSE)
• Exploring the Hyperloop design as a testbed for practicing multi-disciplinary design optimization (MDO)

The choice to use Python over other programming languages is because it has access to numerous libraries for scientific computing and engineering analysis, is open-source, available on all operating systems, has great community support, and can easily be setup for seemless contributor workflow.
This repo rebirth will likely be licensed under Apache 2.0

i've had fun getting it to run on ChromeOS ;)
