/**
Provides hooks to patch the YUI loader on both the server and/or client.
It will facilitate try new things and patches without requiring to wait
for YUI to be released. Here is an example:

    app.yui.patch(require('express-yui/lib/patches/optional-requires'));

In the example above, one of the default patches shipped with with
`express-yui`, is executed on the server and client to patch the
YUI Loader to support a new type of metadata called `optionalRequires`,
which provides an easy way to define requirements for a module that are
not avialable in all runtimes.
