Title: Point2MultVertSS_FaultSource

Description: This converts a point source (single magnitude and probability) into many vertical strike-slip finite (rake=0) ruptures. This is basically a spinning source, but one where there are multiple rupture possibilities along stike as well (the hypocenter is not constrained to be at the mid point). This is a non-Poissonian source. The fault discretization is hard wired at 1 km.

The rupture length is computed from the supplied magScalingRelation. Note that if this is a magAreaRelationship, the rupture length is computed as the area divivded by the seismogenic thickness (rupLength = area/(lowerSeisDepth-upperSeisDepth). Thus, ruptures will have strange aspect ratios for: large mag and small seismogenic thickness (long line source), or small mag and typical seismogenic thickness (narrow but deep rupture). This class does not check for the resonableness of the ruptures in terms of these issues.
