//////////////////////////dataValidation.js Version 1.0//////////////////////////////
/*
To use this datavalidation class, call the static method DataValidation.validateRequest 
from your button that either submits or will be doing the validation of your form. 

Application Requirements: this javascript requires the use of prototype-1.6.0.2.js for the 
utility methods


Specify the following:
d_id: the DIV container that all the form elements you want to validate are contained in.
classToValidate: assign a CSS class to all the form elements you want to have validated 
    (conversely, do not put this class on the for the elements you do not want validated, 
    like Address 2).
errorClass: CSS class defined in your style markup that will be the visual queue for the user 
    to adjust or fix the fields.
    
OPTIONAL FEATURES:

Email Address Validation:

If you have an email form element that you want validated, use [classTovalidate] + 'Email'
Example: ValidateThisCssClass is your normal form element class to validate, 
    ValidateThisCssClassEmail will validate for a valid (well formed) email address.
