PURPOSE: To convert the 42 phash float values for an image to a string of 168 digits

DESCRIPTION: PHASHCONVERT converts the 42 phash (perceptual hash) float values for an image to a string of 168 digits. The string of digits will be listed at the terminal. The string can be stored in a database for later comparison with another string.

NOTE: see phashcompare to compare strings from two different images.

CAVEAT: No guarantee that this script will work on all platforms, nor that trapping of inconsistent parameters is complete and foolproof. Use At Your Own Risk.
