/**
 * Register support of certain features for a post type.

 * All core features are directly associated with a functional area of the edit
 * screen, such as the editor or a meta box. Features include: 'title', 'editor',
 * 'comments', 'revisions', 'trackbacks', 'author', 'excerpt', 'page-attributes',
 * 'thumbnail', 'custom-fields', and 'post-formats'.
 *
 * Additionally, the 'revisions' feature dictates whether the post type will
 * store revisions, and the 'comments' feature dictates whether the comments
 * count will show on the edit screen.
