buildScripts/createClass: automatically figure out the best fitting base class

we need to add multiple (async?) inquirer.prompt() calls to work with the given answers before a user can ask the next questions.

after entering the desired className, the program can then figure out the best matching base class:

1. className includes .model. => data.Model
2. className includes .store. => data.Store
3. className ends with Model => model.Component
4. className ends with Controller => controller.Component
5. default to container.Base
