Subject: Added basic parameter taking overload of
 TransformationFacade::generate * XSLT stylesheets may be provided with a set
 of initial parameters ** these parameters can be provided as the second
 argument to the generate member method in the form of a string to string
 mapping ** the XSLT standard also permitts number and node set types as value
 arguments of such input parameters but this is not supported by this change *
 expanded test transformation to demonstrate this feature
