Agree, it shold be concised.

What we, as geometry developers, at least need:
- a fixed size matrix where N is a template parameter
- should be able to work with large number types (optional, via 
interface or other, see other discussion on mailing list about GMP)
- matrix determinant
- matrix multiplication
- matrix inversion

Most is for transformations. We're now using ublas but indeed a fixed 
size matrix would me more convenient and probably more efficient. For 2D 
geometry a matrix size 3 is necessary.
