Number of times inner iterations were performed.
.. member:: int Solver::Summary::num_line_search_steps
Total number of iterations inside the line search algorithm across
all invocations. We call these iterations "steps" to distinguish
them from the outer iterations of the line search and trust region
minimizer algorithms which call the line search algorithm as a
subroutine.
.. member:: double Solver::Summary::preprocessor_time_in_seconds
Time (in seconds) spent in the preprocessor.
