#28: getDualRays maxNumRays, but only 1 in CLP/CPX

----------------------------+-----------------------------------------------
 In both OsiClp and OsiCpx, getDualRays takes arg=maxNumRays, but only
 returns 1 dual ray. Can the solvers provide more than one? If so, can this
 be implemented (this would be nice)? If not, should there be a maxNumRays
 argument at all? It seems misleading.
