Changes needed for smooth working of algorithms that need no descrete boundaries:
- in SubMeshesComputed(), restrict checking to myDim-1 only
- in AlgoStateEngine(), clean all submeshes in the current on REMOVE_ALGO event
- in CleanDependsOn(), remove call to ComputeStateEngine to avoid repeatitive cleaning
- in ComputeStateEngine(), call CleanDependsOn on the event modifying hyp or algo
  regardless of current compute state
