GenericFrom Provision of Simulation Submodels

[RosOth]

The file GenericForm_ProvisionOfSimulationModels.json cannot be used directly as a plugin in GenericForm. The file name should be GenericForm_ProvisionOfSimulationModels.add-options.json. At least it worked for me. Furthermore, it would be nice to have a section in the ReadMe dedicated to the GenericForms, their purpose and how to use them on the main page.
