 CglLandP needs three methods from OsiClpSolverInterface
 that are in the Osi/devel branch. These are:

   virtual void getBInvARow(int row, CoinIndexedVector * z,
                             CoinIndexedVector * slack=NULL,
                             bool keepScaled=false) const;

   virtual void getBInvACol(int col, CoinIndexedVector * vec) const ;

   virtual void getBInvACol(CoinIndexedVector * rowArray1) const;
