TestSweeper is a C++ testing framework for parameter sweeps. It handles
parsing command line options, iterating over the test space, and printing
results. This simplifies test functions by allowing them to concentrate on
setting up and solving one problem at a time.

TestSweeper is part of the SLATE project (Software for Linear Algebra
Targeting Exascale), funded by the Department of Energy as part of its
Exascale Computing Initiative.
