TwoPhase Method calculator
*New code written for Multiple optimal solution if exists (on 30Oct17).
*removing artificial column from Iteration table (on 17Sep17).
It may be possible, some working problem may not work properly.
If you find any such problem then mail me immediately with the problem,
so i will try my best to improve the software as soon as possible.
