rtree.js

// Usage:
// Put this in a separate file and load it as the first module
// (See https://github.com/jrburke/requirejs/wiki/Internal-API:-onResourceLoad)
// Methods available after page load:
// rtree.map()
// - Fills out every module's map property under rtree.tree.
// - Print out rtree.tree in the console to see their map property.
// rtree.toUml()
// - Prints out a UML string that can be used to generate UML
// - UML Website: http://yuml.me/diagram/scruffy/class/draw
