Description
This is an offspring from ticket:216
Currently (pre0.4) only row-mean-centering is allowed in PCA. Perhaps we could allow other normalizations such as no normalization, median centralizing, z-score, as well as iterative row column normalization.
This should be implemented as a functor. The PCA can then be templatized on this functor, with default being the current one.
