* \brief Iterates hypotesis for all sub-meshes of the given sub-mesh and checks
algo state with the given event. The goal is to address hypothesis those are
not directly affected by changing of an algorithm of the given sub-shape.
It is essential to rebuild propagation chains of such hypotheses, otherwise the chains
are being cleared after editing of the algorithm and never rebuilt again.
* \param subMesh - the main sub-mesh to check sub-meshes of
* \param anHyp - the hypothesis changed on the given sub-mesh, we need to skip it from checking
* \param event - the given event
* \retval SMESH_Hypothesis::Hypothesis_Status - number of unique hypos in aHypList
