create TProfGrid interface for KGrid

I need to convert an old Delphi 7 project to Free Pascal/Lazarus. The original project used a component named TProfGrid that is no longer available. I would like to use the KGrid component and need an interface written for KGrid that simulates the TProfGrid interface so I can easily implement KGrid in the project. I have the documentation for TProfGrid that describes it's methods and properties.
