Changed the interface of QuantileNormalizer?. The interface now has one matrix& and one const&. The former is object for normalization, and the latter is the base for calculating the distributions (Quantiles). The reason to change the interface is to allow normalization based on a nother matrix, e.g., normalizing a test data matrix based on the training data matrix. Also it is more inline with the Centralizer added earlier today. refs #425
