Provides a wrapper around transforming a resource name (filename or URL)
into an absolute URL. By default, this tacks on the module base
to a relative URL and leaves other names alone. It could be used
in other environments to wrap the request with a proxy, such as
when a GWT module runs as a Gadget.
