/*
 * jQuery Form Validator
 *
 * Forms with the class 'validate' are validated.
 * Form must have an id or validation won't work
 * Form Elements to be validated should have any of the following classes to set their valid content
 *
 *   novalidate     - Ignore this field, do not validate - Can be used to temporarily prevent validation of an element
 *   reqnotempty    - Field must not be empty
 *   reqemail       - Must be a valid email address
 *   reqphone       - Must be a valid telephone no
 *   reqalphanum    - Must only be 'A-Z 0-9 ,.+-'*:()=/'
 *   reqalphonly    - Must be 'A-Z ,.-'
 *   reqstrictalpha - ONLY A-Z
 *   reqnum        - '0-9.-' 
 *
