Friends And Related Function Documentation

void CglLiftAndProjectUnitTest	(	const OsiSolverInterface *	siP,
		const std::string	mpdDir
	)		[friend]

A function that tests the methods in the CglLiftAndProject class.

The only reason for it not to be a member method is that this way it doesn't have to be compiled into the library. And that's a gain, because the library should be compiled with optimization on, but this method should be compiled with debugging.
