The TreeMap class implements a tree map representation for data.
For information about treemap, see
http://www.cs.umd.edu/hcil/treemaps/">Schneiderman 1992

A TreeMap is build from hierarchical data, given as a tree
of TMNode. So, the first parameter to give to build a TreeMap
is the TMNode which is the root of the to-be-represented tree.
The tree to be displayed by the TreeMap should be build before the call
to TreeMap, that is the root node should return children
when the children() method is called.

You can get a TMView (herited from JView) containing the TreeMap by calling
getView(). It takes a TMSizeRenderer and a TMDrawRenderer as parameters.
