Tpetra: Port Andrey's getLocalRowView benchmark from MueLu to Tpetra
Created by: mhoemmen
@aprokop wrote a benchmark in MueLu that compares performance of getting local row views with Xpetra::CrsMatrix, Epetra_CrsMatrix, Tpetra::CrsMatrix, and KokkosSparse::CrsMatrix. See Issue #118 (closed) for discussion. The problem is that the benchmark lives in MueLu, and requires enabling experimental build options which are off by default (see Issue #128 (closed), now closed, thanks Andrey!). This motivates me to port the benchmark to Tpetra. The main point of the benchmark will be to compare Tpetra vs. Epetra vs. "raw" Kokkos performance, so I will leave Xpetra out.
