[Cbc] Unable to serialize CoinPackedMatrix

[Ted Ralphs]

There is another COIN-OR project focused exactly on providing Web services
wrapping optimization solvers.

https://coin-or.github.io/OS/welcome.html

There's a lot of nice stuff there for shipping data around, but it's
XML-based. You might also check out this more recent JSON-based project,
which is still in its infancy.

Cheers,

Ted
