Tpetra: sort and merge on insert: CrsGraph::insertLocalIndices
Created by: tjfulle
Sort and merge new indices in
CrsGraph does not sort/merge new indices. Instead, indices are appended to their row of the graph, regardless if they are already present in the row. During
fillComplete, rows are sorted/merged so that duplicate entries are "compressed" out. For
StaticProfile graph, this can lead to running out of capacity due to duplicate entries.
