Tpetra: Add option to specify arbitrary index offset for MatrixMarket I/O of sparse graphs & matrices
Created by: mhoemmen
@trilinos/tpetra Feature request by @crtrott , also desired by @tawiesn for Xpetra.
@crtrott would like Tpetra::CrsMatrix MatrixMarket input and output to let users specify an arbitrary starting offset for row and column indices. Right now, it uses the index base, which is either 0 or 1.
