Remove SectionInfoProtocol, close #103

Removes the superfluous `SectionInfoProtocol` to simplify `DataSource`.
There was really no need for this. If clients aren't happy with this, they
can still implement their own `DataSourceProtocol` instead.

- Removes `SectionInfoProtocol`
- Use `Section` in `DataSource` directly

Other changes:
- Move `DataSourceProtocol` to its own file
- Move `FetchedResultsController` to its own file

 ## Breaking
 
 - Converted to Swift 4.0
+
 - iOS 9.0 minimum now required
+
 - tvOS 10.0 minimum now required
+
 - **Significant renaming refactor:** renamed all "factory" references to "config", see #73 for details and reasoning
     - `ReusableViewFactoryProtocol` --> `ReusableViewConfigProtocol`
     - `ViewFactory` --> `ReusableViewConfig`
     - `TitledSupplementaryViewFactory` --> `TitledSupplementaryViewConfig`
     - Updated function param names `cellFactory:` --> `cellConfig:`
     - Updated function param names `supplementaryFactory:` --> `supplementaryConfig:`
 
+- Removed `SectionInfoProtocol` in favor of using a concrete `Section`. `DataSource` now references `Section` directly. (#103)
+
 ## New
 
 - Added new `DataSourceProtocol` extension convenience method `func item(atIndexPath indexPath: IndexPath) -> Item?`.
