Covering test for add_distributions_mult
Internal representation of probabilities now C-friendly array,offset
Probabilities use array internally
Remove unnecessary route via hash notation for simplest 'complex' die
Enable slow tests, remove non-necessary clone
Add each method to GamesDice::Probabilities
Try over-ride of Travis defaults for JRuby
Extend Travis tests to JRuby 1.9. Add GamesDice.probabilities.repeat_distribution
Add unit test for #repeat_distribution
probabilities.given_ge( x )
Default 0.0 in hash is roughly 5% speed-up
Array slice, not range, is roughly 5% speed-up
Minor speed-up in place sorting
