DynamicCluster

public DynamicCluster(java.util.Map properties, Entity owner)
Instantiate a new DynamicCluster. Valid properties are:
Parameters:
properties - the properties of the cluster (these may be visible to created children by inheritance, but to set properties on children explicitly, use the factory)
owner - the entity that owns this cluster (optional)
