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
