/**
 * sort_files

 * your files based on some sane, and predefined (in the interface) order using the
 * tag information gathered and updated in ampache. Sort_Pattern defines the directory
 * structure and rename_pattern defines the file pattern. This script should allow you
 * to do both or neither. Oooh and allow you to sort with A,B,C,D prefix
 * 
 * Attempt 1 - Do each file one by one and satisfy the needs of each file by its self (this is going to be slow)
