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.

Tried noalias() for collect(), but no real improvement

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.

Switched Matrix::collect() over to a memcpy, but the results weren't actually an improvement

Small optimizations on Matrix::collect(), additional timing capabilities, and now collect() can have dimensions specified to avoid need for lookup.
