Code generation is slow for large prediction horizons #26

This should be fixed. My guess is that it is taking a long time because Matlab is appending characters to very long strings. We should segment the strings so that they do not become too large.

A possible solution is to create a separate string/file for each constant variable of the code.

Performance has been significantly improved in 06e4f8af60e5c7c967c1b2b5025c36ed264f87bd. Its still somewhat slow for large problems, but it might be the best we can do with Matlab unless major changes are made, so I will close this issue for now.
