treesize.py: report sizes of all files and folders in a directory tree

This Python 3.X program generates a report giving the total space taken by each folder and 
file in a directory tree, grouped by type and ordered by size.  Its main goal is to help 
locate candidates for removal when reclaiming disk space.  It also provides a snapshot 
of the contents of your folders or drives.
