Deprecated. 
Runs one iteration of the Simplex method on the given model.

Parameters:
tableau - simple tableau for the problem
Throws:
MaxCountExceededException - if the maximal iteration count has been exceeded
UnboundedSolutionException - if the model is found not to have a bounded solution

solvePhase1
