Provides access for Zoltan2 to Xpetra::CrsGraph data.
test for memory alloc failure when we resize a vector
we assume FillComplete has been called. Should we support objects that are not FillCompleted.
The template parameter is the user's input object:
The scalar_t type, representing use data such as matrix values, is used by Zoltan2 for weights, coordinates, part sizes and quality metrics. Some User types (like Tpetra::CrsMatrix) have an inherent scalar type, and some (like Tpetra::CrsGraph) do not. For such objects, the scalar type is set by Zoltan2 to float. If you wish to change it to double, set the second template parameter to double.
