 In OsiClpSolverInterface, when a lower verbosity is requested, one can
 issue:

 OsiClpSolverInterface* si;
 si->messageHandler()->setLogLevel(0);

 However, there are two problems I noticed.
 1. If multiple calls to initialSolve() are made, the log level value is
 forgotten after each call.  Hence, one has to call setLogLevel before each
 call.  This is maybe just a problem of the documentation.

 2. When the Clp barrier/interior-point method is used, there are still
 trivial messages such as "Switching to dense for the last 12 columns"
 issued, although the log level is set to suppress those.

 Thanks for considering,
 Sebastian
