Not quite. Doing it like this, the function uBlasDenseMatrix::foo is
compiled into an object file, but the member functions of
uBlasMatrix<ublas_dense_matrix> are not. They are compiled every time 
a uBlasDenseMatrix is declared (worst case scenario), or the compiler
tries to do some magic. I had hoped to compile the common matrix types
into the library.
