 * validateForm checks to see that there is some content in each form textfield element that has the "formElementValidate" 
 * style applied to it. formElementValidate may exist as a separate CSS style, defined to distinguish required fields
 * or it may just be a name checked by the validate code, assuming some other CSS style is inherited to specify
 * form field elements.
 * @method validateForm(formObj)
 * @param formObj is pointer to the form object
 * Usage 1: <form name="myForm" method="post" action="return validateForm(this.form.name);" >
 * Usage 2: <input type="submit" value="Submit"  onclick="return validateForm(this.form);" />
