Matrix::multiplyAdd and transposeMultiplyAdd are "level 2" BLAS and speed up the numeric part of the code substantially. Alex might be able to speed them up even more by making them use real BLAS code within Matrix.cpp.

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.
