Documentation:
	Simply call `Bonsai(list)` to turn list into a collapsable tree, where list is
	a reference to an HTMLUlElement. Subtrees are inserted via <ul> elements inside
	<li> elements.
	
	When a tree is opened or collapsed, an event is fired on the root <ul> elements.
	Setting up listeners for "expand" and "collapse" (via addEventListener) or for
	"onexpand" and "oncollapse" (via attachEvent) will capture these events before
	they happen, and subsequently can prevent the event via preventDefault() or by
	setting the returnValue property to false.
	
	Modules are separate bits of functionality which enhance the entire menu. For
	example, bonsai-persistence.js defines a persistence module using cookies. It
	works by utilizing the `Bonsai.addModule(func)` command. func accepts a single
	argument, representing the HTMLUlElement, and otherwise operates entirely
	independent of the Bonsai script itself. The only connection it has to Bonsai
	is that it is called before the creation of the tree itself is considered done.
