Artur's suggestion to address the "No variable" warning in the LpSolver.

[12:17]guimarqu: hey, how do you start column generation when there is no variable in the master ? This happens at first colgen iteration using Farkas pricing
[14:55]Artur Pessoa: To use the solver, I had to add a dummy variable with upper and lower bound equal to zero and disable preprocessing.
