[SCIP] Example of usage of LP Interface to Soplex

[Matthias Miltenberger]

Dear Guillermo,

the answer to your question depends on your use case. If you only want 
to interface SoPlex as an LP solver than you don't need the LPi or even 
SCIP in general. A very short example code is in example.cpp in the 
SoPlex distribution.

If you want to interface using the LPi, though, there is no real example 
code for this - you would have to look at the available methods in 
lpi_spx2.cpp or in any other of the available LPis or look at their 
header file lpi.h.

The advantage of the second method is that you can swap the LP solver 
without having to change your code. I would still recommend avoiding the 
additional overhead of the LP interface and going with option 1.

cheers
Matthias
