Summary: Removing the `IGListSectionType` protocol and adding default implementations into `IGListSectionController`. - `numberOfItems` returns 1 - `cellForItemAtIndex:` asserts (have to return a cell) - `didUpdateToObject:` no-ops - `didSelectItemAtIndex:` no-ops Fixes #168 Reviewed By: jessesquires Differential Revision: D4909585 fbshipit-source-id: 8816702504e3fc0683868914ff4dd20e4af7c166
