1. A context string for biased sampling in Mmsapt can now be provided on the

   command line with --context-string. Not available in server mode yet.
2. Numerous bug fixes related to biased sampling.
3. Biased sampling now checks that the sampling sticks to the bias. If
   the distribution of samples deviates too much from the bias, samples
   whose selection would push the sample distribution even further from the bias
   are not considered, even if that means that fewer samples are chosen in total.
