    MIP_Problem.cc: many optimizations, that mainly affect the Sparse_Matrix implementation
    
    * Row element access is no longer O(1), so use aliases to need only one access.
    * Use get() intead of operator[] for read-only access.
    * Move element access to end of boolean expression, to exploit lazy evaluation.
