Apply a PartitioningSolution to an input.
This is not a required part of the InputAdapter interface. However if the Caller calls a Problem method to redistribute data, it needs this method to perform the redistribution.
| in | An input object with a structure and assignment of of global Ids to processes that matches that of the input data that instantiated this Adapter. |
| out | On return this should point to a newly created object with the specified partitioning. |
| solution | The Solution object created by a Problem should be supplied as the third argument. It must have been templated on user data that has the same global ID distribution as this user data. |
