Remove C++ subgame-perfect equilibrium solver#641
Conversation
This removes the subgame-perfect equilibrium solver in C++ and from the associated command-line tools for `enumpure`, `lp`, and `lcp`. This will be replace in due course with a more flexible and customisable functionality. Closes #637.
* Refactor creation of renderers for DRY. * Minor C++ modernisations

@rahulsavani for you to check please that everything seems to work for you with the affected tools. |

There was a problem hiding this comment.
I tested gambit-enumpure, gambit-lp, and gambit-lcp on master and on this branch.
I can confirm that the -P option is now gone and all three seem to work fine now, so this PR looks good.
I will note however, that with all three CLI tools, I could not get them to work with the -P option on current master. I would always get a "Error: Dereferenced null pointer", as in:
gambit-enumpure -P sample_extensive_game.efg

Not our problem any more though once this is merged in I suppose ;-)
But it is! Now see #647. |

This implements #637. It also includes some minor refactoring of the command-line tool drivers which it was convenient to do while making this change in those files.
