1/**
2 * Namespace implementation for use with jQuery; adapted from Listing 6.16 from
3 * <em>Test-Driven JavaScript development</em>.
4 * 
5 * <blockquote>
6 * 
7 * <pre>
8 * var foo = $.namespace('foo');
9 * foo.bar = function() {...}
10 * foo.baz = {...}
11 * </pre>
12 * 
13 * </blockquote>
14 * 
15 * The implementation can also be used to create separate custom namespaces:
16 * 
17 * <blockquote>
18 * 
19 * <pre>
20 * var custom = {
21 *   namespace : $.namespace
22 * };
23 * </pre>
24 * 
25 * </blockquote>
26 * 
27 * In this example, <code>custom.namespace</code> and <code>$.namespace</code>
28 * remain separate and distinct.
29 * 
30 * @param namespaceString
31 *          {string} the namespace to retrieve or create. Nested namespaces
32 *          should be delineated with '.', for example 'outer.inner'.
33 * @returns {object} the resulting namespace, which is created if it does not
34 *          already exist

38  var levels = namespaceString.split(".");
