Add CalculateRollup function to early binding of a rollup field.
It would be great if I could Execute a CalculateRollupRequest if the field is a rollup field. Currently I have to extend the proxy class and so I could call the function. It could work similar to how lookup fields can RetrieveProxy<T> i.e. contactRecord.new_rollupfield.Rollup(OrganizationService) would execute the function.
