This bt5 contains all code related to the parameter editor, include the testing dialogs and samples.

   The goal is evolved the implementation and keep code specific separated from the rest of the implementation (so if UI can change and we keep a "generic" implementation.

   Test form was included on Software Product Module due security reasons (so be allowed to be used as normal user).
