[Toon-members] Eigen

[Georg Klein]

Just wondering if you've come across Eigen? It seem to be similar to TooN 
in design - has some things TooN doesn't like explicit use of SSE, and 
likewise TooN has some things it doesn't like SE3s.

Anyway an interesting point which emerges from it is that apparently the 
LGPL v3 is compatible with header-only code, as confirmed by a letter from 
the FSF.
