I used the AMD module system to build the application, specifically I use require.js for a module loader
There are three seperate modules
A module that stores all objects and performs calculations on those objects at a set speed and accuracy.
There's a separate branched called 'barnes-hut' which has an implementation of the barnes-hut algorithm. Supposed to be a plug and play thing where you can toggle it for greater speeds
The old gui and render modules have been scrapped for a new combined one that doesn't have the same annoying problem of shared state of things like the cursor or camera. Currently being worked on, sorry for any annoyance
