void distributeEntities()
DynamicGroup.ENTITY_FILTER into uniquely-named
buckets according to the BUCKET_FUNCTION.
A Group entity is created for each required bucket and added as a managed child of
this component. Entities for a given bucket are added as members of the corresponding group.
By default BasicGroup instances will be created for the buckets, however any group
entity can be used instead (e.g. with custom effectors) by specifying the relevant entity
spec via the BUCKET_SPEC config key.
Entities for which the bucket function returns null are not allocated to any
bucket and are thus effectively excluded. Buckets that become empty following re-evaluation
are removed.
