[Help-glpk] adding --csv output

[Kevin Hunter]

Hullo Andrew, List,

I had need of an unambiguous version (for machine parsing) of the output 
provided by the glp_print_* functions.  Consequently, I've created an 
equivalent set of glp_csv_* functions.  With this patch, one can use a 
--csv <file> flag:

$ glpsol --lp test.lp --csv solution.csv

This patch adds three glp_csv_{sol,ipt,mip} functions and a couple of 
miscellaneous helper functions to the glpk-4.45 tarball.

I'm rather new to GLPK's code base, but I think I've my ducks in a row. 
 Specifically, Xypron, if you have some time, I would much appreciate a 
code review.

Thanks, and I hope this proves useful to others.

Cheers,

Kevin
