Title: Fix for Issues #163 and #178

Rationalize usage of size and value_type computation so less box and raw
generator overloads are used.

- clarified box usage guide
- Provide premade metafunction for common size or value computations
- removed some useless computation in size and value_type
- removed the need of add_settings
- generator has been moved to details:: and is not advised to be overloaded.
