Creating extension class adds extension class from another model to project

[shashisadasivan]

Example to follow
if a extension class exists, then that is added to the project. However, it needs to be a part of the current model
Currently, it copies the class from the other model and then adds it to the project (This also adds the object as a new one in the current model)

e.g Table > SalesLine
From designer select Addins > Create Code extension
This adds the existing class RevRecSalesLine_Extension (as a copy into your model) This class is a part of Revenue recognition model. A copy of this class gets created in your model with the same name.
