simmer 3.3.0

New features:

• New join activity to concatenate trajectories (#50).
• Batched generation: the generation function can return more than one interarrival value at a time (#65).
• Add the option queue_size_strict to add_resource to guarantee the queue size limit with preemption (#59).
• New select, seize_selected and release_selected activities (#52).
• Modify resources (capacity, queue size) from inside a trajectory (#66).
• New leave activity (#63).

Major fixes:

• Fix per-resource activity time monitoring (#67). The problem emerged when an arrival revisited a resource and it was enqueued. An uninitialised variable could lead to an activity time greater than end_time - start_time. All versions 3.2.x are affected by this bug.

Minor changes and fixes:

• Fix the description of preemptible in the documentation of seize and force preemptible to be equal or greater than priority (#53).
• Reset finite generators (#51).
• Fix the handling of a capacity change when the new value is infinite (#60).
• Various doc fixes (#61).
• Change branch's merge parameter name to continue. The old name is deprecated (#57).
• Use match.arg() in multiple-choice arguments (#55).
• Fix branch backwards linking and count (#56).
• Split release in two steps to deal properly with capacity changes at the same point in time (#64).
• The convenience function every is deprecated due to #65.
• Update and extend previous vignettes.
