nr_samples_per_proposed_particle variable

[EmadAlamoudi]

I was discussing with Jan and he proposes changing the variable nr_samples_per_parameter into nr_samples_per_proposed_particle to avoid confusion that may be caused by the term parameter in that context.

This variable will hopefully get deleted anyway soon, probably when we discard the sql database.

Closed as merged.
