		The main aim is to make input validation expressible in a simple format.

		The results are provided as an object that makes it easy to handle missing and invalid input.

	Usage

		var results = dojo.validate.check(form, profile);

	Profile Object

		var profile = {
			// filters change the field value and are applied before validation.
			trim: ["tx1", "tx2"],
			uppercase: ["tx9"],
			lowercase: ["tx5", "tx6", "tx7"],
			ucfirst: ["tx10"],
			digit: ["tx11"],

			// required input fields that are blank will be reported missing.
			// required radio button groups and drop-down lists with no selection will be reported missing.
			// checkbox groups and selectboxes can be required to have more than one value selected.
