	Usage Note:
	-----------
	Do not use both ajaxSubmit and ajaxForm on the same form.  These
	functions are intended to be exclusive.  Use ajaxSubmit if you want
	to bind your own submit handler to the form.  For example,

	$(document).ready(function() {
		$('#myForm').bind('submit', function() {
			$(this).ajaxSubmit({
				target: '#output'
			});
			return false; // <-- important!
		});
	});

	Use ajaxForm when you want the plugin to manage all the event binding
	for you.  For example,

	$(document).ready(function() {
		$('#myForm').ajaxForm({
			target: '#output'
		});
	});

	When using ajaxForm, the ajaxSubmit function will be invoked for you
	at the appropriate time.

/**
 * ajaxForm() provides a mechanism for fully automating form submission.

 * 1: This method will include coordinates for <input type="image" /> elements (if the element
 *	is used to submit the form).
 * 2. This method will include the submit element's name/value data (for the element that was
 *	used to submit the form).
 * 3. This method binds the submit() method to the form for you.
 *
 * The options argument for ajaxForm works exactly as it does for ajaxSubmit.  ajaxForm merely
 * passes the options argument along after properly binding events for submit elements and
 * the form itself.
