Summary of the Grigr2002 level set

Each solver is tested separately to ensure that they don't compete for system resources.

Though some people might be interested in how long it takes to solve a given level and/or how good the solution is (optimal or not),
this summary disregards all timing associated with solving the levels and solution statistics.

These tests are mainly for gauging solvability, not timing nor how good the solution is.

All solvers combined solved 40 of 40 levels.
