Your TreeIO will write its trees to the file or filehandle you give it. 
But you haven't given it one. Give it one are write_tree() will then 
cause the tree to be 'printed' there.

If you want the trees stored in a string so you can print() them, there 
are ways to open a filehandle onto a scalar variable.
