Make includable

[salexzee]

I now want this to have the ability to be included in a project. It would be much easier to work with instead of just having to reference it all the time. The Javascript could look something like this.

$.getScript("getTreeJSON.js", function(){ // All code is contained in here. });

This specific code would force me to keep jQuery as a part of the project for a bit longer unless I go with the pure Javascript version.

Not needed. I think it works fine for now.
