emplp10.gms : Poorly-scaled model - small matrix entry implies large x using EMP


This model tests lp10 from the Test Library with solver EMP. In the first test
EMP generates a standard scalar model which is solved by the default lp solver.
For the second test EMP rewrites the model as MCP and solves it with the default
MCP solver.
