Added the logarithmic/linear GridSearch.

Divides the intervals both logarithmically and lineary and tries all
combinations of the options.

When the boolean options for search agents works, they can be added and
the lin or log divisions can be run independently (thus this agent is a
generalization of ChooseXValues).
Added new Recommender -- NMTopRecommender

Selects the best N results for the closest M files. The best agent is
selected as the most often used agent on those M files.

The average and stardard deviation of individual option values is computed and the recommended
agent uses the range <avg - 2*sd,avg + 2*sd> for each of these options.

Options with sd = 0 use the value of avg (no range, immutable).
