PkgTree - A tree class for displaying packages
The package tree class handles the various item classes and provides
them with some utility functions. It also handles all of the user
interaction for the item classes.
To speed up the rendering we cache the location data from the column
bar, it is regenerated each time the Tree's render function is called.
