	File:  oLoginAuth.phi [v2.03]
	Purpose:  Nathan's standardized but extensible login/authorization check/enforcement/prompt handling module.
	Created:  10/10/2001 - Locke Enterprises (iLocke.com)
	Modification History:
		* 12/7/2004 - Nathan - legacy in-line code concepts � 2001-2004 molded into this new class object
		* 05/23/2019 - Nathan - adapted for responsive template
		* mm/dd/yyyy - [name] - [comment]
	Prerequisites:  NDB, PHP4 w/ register_globals=on / magic_quotes=off
	Notes:
		Still needs several additional callbacks - this version is specific to W2G customers.
		The plan is to have a simple and callback login method.
		Simple just gives it a template SQL string:
			(numerical) SELECT ID FROM {TABLE} WHERE {USER_FIELD}='{USER_KEY}' AND {PW_FIELD}='{PW_KEY}'
			(object) SELECT * ... / this method registers the array into the rInfo of the session object
		Complex runs a callback and logs the user in on its own.
