def self.validates_uniqueness_of_with_nilification(*args)
	#	NOTE ANY field that has a unique index in the database NEEDS
	#	to NOT be blank.  Multiple nils are acceptable in index, 
	#	but multiple blanks are NOT.  Nilify ALL fields with
	#	unique indexes in the database. At least those that
	#	would appear on a form, as an empty text box is sent
	#	as '' and not nil, hence the initial problem.
	#	The first one will work, but will fail after.

	#	ONLY IF THE FIELD IS A STRING!
