Reimplemented matrix::householder_update using GSL and BLAS, you'll need to edit Makefile.am to enable the new version -- see email

Changed the interface on Matrix::column() so that it uses the one in our library (now called column_() ) rather than the boost default. Currently, our implementation just uses the boost default, but this may change due to timing results.

Checked Matrix::collect() with different timing metric, and memcpy has approx 25% speedup over original version. Matrix_range is slower or the same speed as the original version.

Implemented a version of collect() using matrix_range, but it had worse performance than memcpy. New version of vector_scale[column] with new pointer arithmetic implementation for approx 20% improvement.
