*Wk1 summary:* cookbook - QDA; hierarchical clustering cereal cmake cereal prototype with `SGVector` linalg propotype with CPU `dot`
*Wk2 plan:* cookbook - multiclasslinearmachine_modular, multiclasslogisticregression_modular cereal on `parameter`,` SGMatrix`, `SGString`, XML, binary etc.. linalg - finish GPU part. polish details (or change framework) Everything was slower than I thought in the 1st week. Now I am familiar with stuff and hopefully be more productive this week! Best, Pan Deng
