* http://nashruddin.com/Remove_Directories_Recursively_with_PHP
* This function removes a directory and its contents. Use with care; no undo!
* The function determines if argument is a regular file or a directory. If it is a regular file, it will remove the file. If it is a directory, it will remove its contents first by calling the function itself, and then removes the empty directory.
* This requires PHP 5 (because of 'scandir').
