Inexperienced jurors distribution

[yurloc]

There is a requirement for jurors who have never voted before to act as non-voting members to gain their first experience. Only after that they will be assigned as regular jurors.

From the scheduling point of view this means that inexperienced jurors have -1 rounds available for being voting jury members. To avoid having this negative impact on overall jury capacity it has been proposed to allow for a variable jury capacity: typically N-1 in the first round, where the majority of inexperienced jurors are supposed to gain experience, and N in all subsequent rounds.

This requires:

• [x] rule that prevents assigning an inexperienced juror in the first round he or she is available
• [x] variable jury sizes per round
• [x] distributing non-voting jurors to juries + UI representation
• [x] including non-voting jurors in PDF reports
• [x] storing jurors on non-voting positions in schedule CSV and recognizing them during import

Just for the record, inexperienced jurors are scheduled correctly since 33c430d003b03d8a078da89a38cca637ac8ba768.

With the variable jury sizes (per round) that have been added recently, it is possible for example to set smaller jury size in round 1 so that juries can be filled without using inexperienced jurors and, at the same time, have bigger jury size in later rounds where inexperienced jurors can be utilized because they took part in round 1 (as non-voting).
