[Couenne] Questions regarding the installation and usage of COUENNE

[Ted Ralphs]

Hi Patricio,

Sorry for the out-of-date README. I haven't gotten to updating it, since we
moved to git. The documentation here

https://coin-or.github.io/user_introduction.html

should answer many of your questions. The fetch and build process is fully
automated so you shouldn't need to worry about many of the things you asked
about. You can build with clang or gcc from homebrew, as you wish. One of
these days, we will have a homebrew recipe for couenne, but we haven't
gotten to that yet.

Let us know if anything is still not clear after reading the
documentation and trying to do the build. Then we can answer any remaining
questions. Feel free to open issues for any problems as well.

Cheers,

Ted
