Crowd Levels are a concept that allows to make an infinite number of iterations with simualtions and caches/layout.
The principle is that a cache and its layout can be re-imported into a
new simulation, where it will be replayed on each entity as if it was a
simple animation, trough a Motion behavior.
Once the cache is replayed in the simulation, it is possible to add new
behaviors in parallel, create new entity types, or anything that is
usually done in simulation.
Golaem levels workflow
Levels are handled by the Crowd Levels Manager: it allows to navigate trough levels, and to add new ones.
When creating new golaem nodes at any level, they will automatically be grouped under a glmCrowdLevel_n Maya node, and inactive levels will be greyed out in the outliner:

There are a few limitations when importing a simulation cache within a new level simulation.
