GMPL can be used to define models, which can be imported via method
OsiSolverInterface->readGMPL.
GMPL can also be used to define post processing, which can be used for
efficient output of the results of an optimization run.
Unfortunately method readGMPL always calls mpl_terminate(gmpl). Hence it
is not possible to execute the postprocessing of the GMPL model.
I suggest to add an optional parameter to readGMPL which allows to keep
the model opened and a new method to OsiSolverInterface to execute the
postprocessing phase in GLPK.
