PCHPDDMSetRHSMat

Sets the right-hand side matrix used by PCHPDDM for the concurrent GenEO eigenproblems at the finest level. Must be used in conjuction with PCHPDDMSetAuxiliaryMat(N), so that Nv = lambda Bv is solved using EPSSetOperators(N, B). It is assumed that N and B are provided using the same numbering. This provides a means to try more advanced methods such as GenEO-II or H-GenEO.
