Adding an interface to the SysOperation framework

We can do a lot by just decorating the contract data methods but, sometimes, we need more control. This recipe steps through adding more control to the user interface created by the SysOperation framework.

Getting ready

We just need an existing SysOperation process class that we wish to add a customized interface to.
