custom type support

matrix template has incomplete support for custom types or it was broken.

can try it with this https://github.com/ohhmm/openmind/blob/master/omnn/extrapolator/Number.h

Start by reproducing the build failure with omnn/extrapolator/Number.h, then read omnn/extrapolator/Extrapolator.h and the references from Extrapolator.cpp and System.cpp. Trace the Boost uBLAS lu_factorize instantiation shown in the error and determine the scope of custom-type support. Done means the Number example builds successfully through this path.
