double-pendulum 1.0.16

A small double pendulum simulator

Features

• As mentioned, able to simulate multiple pendulums at once.
• Able to specify the weight and mass of pendulums to create different butterfly effects.
• Uses equations from here.
• If -s is used, it grabs system specs and displays them (hi r/unixporn)
• Obviously a lot could be done to it (see below the Args), Any contributions are appreciated)

TODO

Note I will not be updating the words on this TODO, but rather just checking them off, as a nice front page reminder of the work done :)

• Add windows functionality
• Add more functionality to arguments (epsilon, weight1, weight2)
• General cleanup of variable names
• Improve efficiency (esp in lists)
• Add colors :)

If you have any suggestions, or anything you'd like to add, just open a PR :)
