Command line interface for the solver

[Vlad-Shcherbina]

The one that supports all the flags organizers require to support (like -p, -c and whatnot)

Obviously, requires a solver.
But it would be nice to have a skeleton in advance. One that parses all the flags and inputs, and outputs dummy solution (in the correct format and all).

Committed first skeleton of the tool.

The core is done.

I'm particularly concerned that print()s in the code can corrupt the output so I:

• redirect stdout to stderr when the solver runs
• added a script to make sure the output of the tool is valid json

$ production/play_icfp2015 | production/check_solution_is_well_formed

It should print nothing.

$ echo garbage | production/check_solution_is_well_formed

It should shout at you.

To run it:

$ production/play_icfp2015 -f data/qualifier/problem_12.json -c 3 \
   -p "tsathoggua" -p "Yuggoth" 2> /tmp/out | production/golden/submit /dev/stdin

[martignlo]

To run the tool on all problems and with all power phrases:

$ production/run_play_icfp2015 2> /tmp/log

[martignlo]

To run all and submit:

$ production/run_play_icfp2015 2> /tmp/log | production/golden/submit /dev/stdin

The log contains at the end the scores and the total runtime. To see the runtime of each problem instance:

$ grep 'Problem.*solved' /tmp/log

Problematic runs have 0 score:

$ grep 'Problem:.*Seed:.* Score: 0' /tmp/log
