Registers a module with the YUI global. The easiest way to create a

with any configuration info required for the module.
@method add
@param name {String} module name.
@param fn {Function} entry point into the module that is used to bind module to the YUI instance.
@param {YUI} fn.Y The YUI instance this module is executed in.
@param {String} fn.name The name of the module
@param version {String} version string.
@param details {Object} optional config data:
@param details.requires {Array} features that must be present before this module can be attached.
@param details.optional {Array} optional features that should be present if loadOptional
is defined. Note: modules are not often loaded this way in YUI 3,
but this field is still useful to inform the user that certain
features in the component will require additional dependencies.
@param details.use {Array} features that are included within this module which need to
be attached automatically when this module is attached. This
supports the YUI 3 rollup system -- a module with submodules
defined will need to have the submodules listed in the 'use'
config. The YUI component build tool does this for you.
@return {YUI} the YUI instance.

/**
Adds a namespace object onto the YUI global if called statically.
// creates YUI.your.namespace.here as nested objects
YUI.namespace("your.namespace.here");
If called as a method on a YUI <em>instance</em>, it creates the
namespace on the instance.
// creates Y.property.package
Y.namespace("property.package");
Dots in the input string cause `namespace` to create nested objects for
each token. If any part of the requested namespace already exists, the
current object will be left in place. This allows multiple calls to
`namespace` to preserve existing namespaced properties.
If the first token in the namespace string is "YAHOO", the token is
discarded.
Be careful with namespace tokens. Reserved words may work in some browsers
and not others. For instance, the following will fail in some browsers
because the supported version of JavaScript reserves the word "long":
Y.namespace("really.long.nested.namespace");
<em>Note: If you pass multiple arguments to create multiple namespaces, only
the last one created is returned from this function.</em>
