Move files from multiple directories to one.

moveFiles.py

#! /usr/local/bin/python3.2

# Moves files from multiple directories to one, and renames them if necessary.

# WHEN IS THIS SCRIPT USEFUL:
# If you have files in multiple directories, say ABC, ABC-1, ABC-2, 
# then all the files from the directores will be moved to directory ABC
# and the other directories would be removed.
# If a file with that name already exists, it will be renamed and then moved.
# Renaming: <filename> ==>  ABC--<filename>--<some_number>
