• String feature factory: merge PR for now (string_features factory) so we can start adding string meta examples. Then later we can add a smarter factory and grep change all the factory calls
• CRTP pattern to be tried in dispatching feature types
• General: static typing of all shogun C++ interfaces might make moving to smart pointers (some) much easier, as there is not the problem of up/down-casting we have now (Some<CLinearRegression> not compatible with Some<CMachine>)
• Wuwei continue Micheles PR on feature view. Use raw pointers for now
