[SCIP] Exporting the solution to a file.

[Gregor Hendel]

Dear Daniel,

I can definitely tell that this file is open. However, you may have 
overread the profi advise to your stack overflow question to check if 
there is a best solution. Please check this using either 
SCIPgetBestSol() or SCIPgetNSols() prior to calling SCIPprintBestSol().

Happy printing,
Gregor
