	description	:	creates string of specified date in specified format
	last updated:	2002.06.11 - dsa - added "shortboth" format code
					2002.06.22 - dsa - added "7" code for timezone
					2002.08.31 - dsa - modified format "day" to allow for theDate
					(passed in) to be a single value [0..6 -- i.e., value from .getDay()]

	dateFormat legal values:
	full		= "dddd, mmmm dd, yyyy @ hh:mm ap"
	std			= "ddd, mmm dd, yyyy @ hh:mm ap"
	day			= "dddd"
	date,
	longdate	= "mmmm dd, yyyy"
	shortdate	= "mm/dd/yyyy"
	intldate	= "dd-mmm-yyyy"
	time,
	longtime	= "hh:mm:ss ap"			[civilian time]
	shorttime	= "hh:mm:ss" 			[00-23 hours]
	stdtime		= "hh:mm ap"
	shortboth	= "mm/dd/yyyy hh:mm:ss"
		** example date used in below examples: 01/04/2002
	other	=	"0"	= extend next format to full form ("00" = "&nbsp;")
				"1" = day of week (ddd: "Fri"/"Friday")
				"2" = month of year (mmmm: "Jan"/"January")
				"3" = month of year (mm: "1"/"01")
				"4" = day of month (dd: "4"/"04")
				"5" = year (yyyy: "02"/"2002")
				"6" = shorttime/longtime (see above)
				"7" = timezone (i.e., "GMT +/- hh00")
				"8" = day time (i.e., "morning", "afternoon", etc.)
				"@" = "@ " but only if time present within theDate

This routine will validate the form object passed in as the (only) argument.

It will verify that all text boxes have been filled in.
However, if the name of the field is prefixed with "qty", then the contents will
   *also* be verified to contain ONLY digits ('0'-'9', but not '-' or '.').
However, any field with "?" as the only contents will be valid, even if qty field.
However, if the name of the field is prefixed with "opt", then the contents will
   be considered optional and may be left blank (w/ no validation performed).

It will verify that all radio buttons have been set.
They will be given an alert message summarizing which rado buttons are unset.

If there is a text field named "email", the contents will be verified as
   a valid email address ("username@domain.tld"), empty not allowed.

Any text field that is considered invalid will have it's background color changed
to light red, indicating a field the user needs to correct.  They will also be
given an alert message summarizing which fields are incorrect.

Example:
	field type: text	field name: userName
	field must contain (any) text; e.g., "qwerty"

	field text: text	field name: email
	field must contain valid email address; e.g., "myname@mail.com"

	field type: text	field name: r.comments
	field may NOT be left blank

	field type: text	field name: qtyMembers
	field must contain text; digits only; e.g.,: "174" ("342.4" is invalid)
