Best-known quality only VRP solutions #2705

Some papers and websites report only the qualities of best-known solutions. However, we can only import best-known solutions with known routes.

The import mechanism should be adapted to support quality-only best-known solutions so that we can display the best-known quality.

r14478

Updated the Homberger benchmark best-known solutions (from http://www.sintef.no/projectweb/top/vrptw/homberger-benchmark/).

Added a distance-only option for the best-known solutions in the SolomonFormatInstanceProvider (which is the base for the Homberger benchmark set).

r14481

Added best-known quality-only solutions for the Solomon benchmark set (from http://web.cba.neu.edu/~msolomon/problems.htm).

The best-known-quality is not set to null if the BestKnownSolution is null after the evaluation. Instead it is reset if the evaluator changes.

r14482

Added best-known solutions to the Solomon benchmark set.

When the distance matrix is calculate internally for performance optimization, the DistanceMatrix-parameter is not set anymore, because this matrix is actually not part of the problem instance. This also fixes issues that qualities of known-solutions are wrongfully discarded due to a problem instance change that is actually not a change.

r14504 Fixed localization issues in some format providers.
