23  * A dummy servlet context object that simply forwards all

25  * This allows for greater flexibility when testing. For
26  * example, if the a test needs to be run that changes the
27  * context, however, those changes should not be apparent
28  * to the next test, then a sub-class of this class could
29  * simply use a local hash for all the context attributes.
