// This script checks to see if everything with a class of "required" is filled in.
// It does not check for valid information, only that something is entered.
// If you need more validation, please use another include.
// USAGE: 
// (1) make sure that the main jQuery .js file is included.
// (2) include this .js file in the <head> of your document.
// (3) in your <form> tag, include:   onSubmit="return basic_form_check();"   i.e. <form name="form1" method="post" action="process_form.php" onSubmit="return basic_form_check();">
// (4) give everything you want to be "required" a class of "required"
// (5) anything that is blank will be given an additional class of "error". 
// If you want your boxes to indicate which ones have failed, create an "error" class in your css.
// This script will also put the browsers focus/cursor into the first empty required field.
