Make it simpler to debug

[JasonMarechal25]

When there are issues in xpansion, debuging can prove to be difficult.
Let's say an error occurs in Problem Generation, you need :

• Find the c++ command line, probably by adding a "print" in driver
• Ensure to have the proper data structure (archive, output, lp dir, etc.)

To simplify this some actions can be taken :

• Drivers shouldn't "do" anything, they can verify data though.
• Command line interface should be simplified. A lot of parameters can be defaulted to some values
• Invert c++/python: have a c++ executable (for debugging purpose) that call python.

Tasks:

• Handle directory creation in c++ for problem generation #700
• Have default parameters for "fullrun" command line #701
• Have simpler/less parameters for "fullrun" command line #702
• Have simpler/less parameters for ProblemGeneration #703
• Don't touch benders command line API

You can erase fullrun from this, it’s not properly an Xpansion step. I suggest To not duplicate responsibilities between c++ and Python. Thus, i propose focusing only on user’s friendly features

Debugging is our burden
