#36: CglTwomir generates invalid cuts

 Priority:  major       |   Milestone:               
Component:  CglTwomir   |     Version:  release 0.5.1

------------------------+---------------------------------------------------
 In determining whether a row is bounded, the DGG_getData function uses a
 fixed value of DBL_MAX rather than the OsiSolverInterface object's
 getInfinity() value.  This resulted in invalid cuts with
 OsiCpxSolverInterfacel.  This bug may affect other Cgl generators as well.
