Epetra_Import_Util: The Epetra ImportUtil Wrapper Namespace.
The Epetra_Import_Util namepsace is a collection of useful functions for data import. The goal of this is to rmevoe code duplication between Epetra and EpetraExt.

UnpackAndCombineIntoCrsArrays.
You should call UnpackWithOwningPIDsCount first and allocate all arrays accordingly.
Note: The SourcePids vector (on input) should contain of owning PIDs for each column in the ColMap, as from Epetra_Util::GetPids, with the "-1 for local" option being used.
Note: The TargetPids vector (on output) will contain of owning PIDs for each column in the ColMap, as from Epetra_Util::GetPids, with the "-1 for local" option being used.

LowCommunicationMakeColMapAndReindex.
If you know the owning PIDs already, you can make the colmap a lot less expensively.
Note: The owningPids vector (on input) should contain of owning PIDs for each column in the ColMap, as from Epetra_Util::GetPids, with the "-1 for local" can be used, or not, here.
Note: This method will return a std::vector of the RemotePIDs, used for construction of the importer.
