[Coin-discuss] Revision of GLPK

[Joseph Young]

	I updated OsiGlpkSolverInterface.cpp to be compatible with the new 
API used in v4.4 and 4.5.  However, there are a few odd quirks:

In unitTest (OsiGlpkSolverInterfaceTest: 495), assert(eq(ev[0],3.0)) was 
failing.  In appeared as though getMatrixByRow was reading in the rows in 
reverse order.  This should not have happened because this function is 
correctly reading in the elements and indices from GLPK's data structures.  
So, it looks like there may be a problem with the copy routines elsewhere.  
Right now, I have a hack to fix this, but someone might want to look at it 
further.

In unitTest (OsiSolverInterfaceTest: 3275), is segfaulting for unknown 
reasons on OsiSolverInterface *s=emptySi->clone().

	Anyway, you can play with the new version if you'd like.  Since 
OsiGlpkSolverInterface.cpp is around 2500 lines, it's probably not prudent 
to post it here, so would anyone like a copy?
