 *  This function will provide a standard validation for all test drive forms.  The function

 *  The function will provide an alert message, and then return false after finding the first
 *  unmatching element.
 * 
 *  Note:
 *  Form inputs should be set up as follows
 *   <input type="xxxx" lang="[true|false]" id="[expected]" title="[description]">
 *   lang -> if lang is set to true then this input will be ignored, if false then it will be validated
 *   id -> if the user input does not match this field then the validation will fail
 *   title -> the field description to be used in alert messages

 * REQUIREMENTS: If an element is being validated it must contain a label with the same

   textbox TXTName to be validated, create a label with the ID TXTName_Label.

   It validates each field by comparing its value to the elements title. Each validation
   message is displayed in an alert. For required checkboxes it checks to see if it is checked
   if not then it alerts the corresponding alert message
