I also think it is great having OsiGlpk running wiht unitTest.

I forgot to mention that the testing in unitTest.cpp and
OsiSolverInterfaceTest.cpp really helped me improve OsiGlpk,
especially by helping me identify several significant errors.

Thanks to everyone who has spent time working on the test sets.
