/*
	Include file - Javascript code for all other php files"
	-----------------------------------------------------
	Code by Hari Szovik - szovik.hari@ge.com - May 2005 -
	-----------------------------------------------------

	The code snipets below were developed for the purpose of having "real-time"
	value consistency checking and correction while the user types the value (not
	only when the focus leaves the fields), according to defined "natural" rules like
	"numeric only", "numeric with comma (%)", "currency only", "minimum/maximum" and
	according to project defined specific rules to meet expectations of relational
	behaviors of input controls. These checkings happen right at the moment when the
	user types, and	not when the user leaves the fields, to help guide the user better
	into not entering erroneous values. The checkings take into account typed characters,
	inserted characters, and pasted characters.

	These codes, mainly the procedures defined under specific "natural" logic can be
	reused in other pages, and are not specifically "tied" to the php page.
	Only a very few minor changes might be necessary to reuse these codes on
	other pages.
