/**
 * File: Javascripts/SimpleValidation.js
 * This script is used to do simple validation on a form. It basically
 * just makes sure all the fields have values. To force a field to be
 * skipped you can either set it to disabled, or add it to the 
 * VAL_SKIP_FILEDS object using the form name as the key. For example:
 * (code)
 * VAL_SKIP_FIELDS["ADDRESS_2"] = 1;
 * (end code)
 * will skip the field named ADDRESS_2
 *
 * To use the script, add it to the onsubmit attribute to the form element
 * and pass in the form name (defined by the name attribute on the form element)
 * (code)
 * <form ... name="mainform" ... onsubmit="return simpleValidate('mainform');" ...
 * (end code)
