A simplex code with dual and primal variants
 A pre-solve capacity in the Coin directory for use by other solvers as well
 An extensible matrix format which allows for specialized formats, e.g.,  an all ones matrix
 Virtual message handlers and event handlers for sophisticated users
 Dual and primal ranging
 An interior point solver
  Three solvers for optimizing a quadratic objective function over a linear constraint set:
 (i)  an interior point solver, (ii)  a simplex solver,  (iii) sequential LP solver
 Extensible matrix formats for more ambitious structures, e.g. a GUB matrix
