Timing Interface

These functions are used to get timings from class internal computations.

The values are stored in a user defined concepts::InOutParameters structure in different arrays (see setTimings). These arrays can be grouped into a table for easier postprocessing with

table.addMap(concepts::ResultsTable::DOUBLE, "jacobian", output);
table.addMap(concepts::ResultsTable::DOUBLE, "whole_sumfact", output);
std::ofstream ofs("table.gnuplot");
