v1.0: First full release

Looks through a form for elements with class names and validates them accordingly. Requires form elements have 'name' attribute. Elements which fail validation are given the class 'bad', which can be styled to suit, and a message in a <span class='bad'> is appended following the element.

Validation classes for form elements are:
    required: Only elements with this class attribute will be checked
	alpha: Alphabetic  (A-Z, a-z) characters only
	alphaSpaces: Alphabetic characters and spaces
	alphaNumeric: Alphabetic and numeric (0-9) characters
	alphaNumericSpaces: Alphabetic and numeric characters and spaces
	noAlpha: All characters except alphabetic
	noNumbers: All characters except numeric
	number: Must be a number, whole or decimal
	integer: Must be a whole number
	decimal: Must be a decimal number
	numberNonNegative: Must be zero or a positive number
	numberPositive: Must be a positive number
	date: Must be a date. Accepts formats: mm/dd/yyyy, mm/dd/yy, mm-dd-yyyy, mm-dd-yy
	email: Must be an email address
	ssn: Must be a US Social Security number XXX-XX-XXXX
	zip: Must be a US Zip code, +4 optional
	usPhone: A US phone number, with area code
    usPhoneNoArea: A US phone number, without area code
	hexColor: A hexidecimal color code, optional # prefix
	ordered: Must be a value of 'true' to not trigger error 'These must be in the correct order'

EXAMPLE:
	JavaScript:
	$('form#formName').cosValidate();
	
	HTML:
	<form id="formName">
		<input type="text" name="firstName" class="required alphaSpaces" />
		<input type="submit" name="sendForm" />
	</form>
