Ublas : |

Geez, thanks for all your help guys. Don't all be bombarding my inbox
with some answers.
Anyways while you all have remained silent, the problem has been
resolved. I reinstalled Boost 1.29.0 and the SLAM code now works with
the uBlas that came with that. Unless there's a really good reason to
upgrade Boost, I'm happy...for now.
