Comment:
Fixed in trunk by implementing {{{setHintParam}}}. Did not use
{{{lib_set_print_hook}}} idea. This would set a property of the underlying
solver, not the OGSI object, so there would be real problems ensuring that
the message handler held by glpk still existed (the supplying OGSI object
may have been deleted, taking the message handler with it).
{{{OsiDoReducePrint}}} now sets glpk and OGSI print levels. Hints for
presolve, use of dual, and scaling also implemented.
