*
* The capability_type argument can optionally be registered as an array, with
* the first value being singular and the second plural, e.g. array('story, 'stories')
* Otherwise, an 's' will be added to the value for the plural form. After
* registration, capability_type will always be a string of the singular value.
*
* By default, eight keys are accepted as part of the capabilities array:
*
* - edit_post, read_post, and delete_post are meta capabilities, which are then
* generally mapped to corresponding primitive capabilities depending on the
* context, which would be the post being edited/read/deleted and the user or
* role being checked. Thus these capabilities would generally not be granted
* directly to users or roles.
*
* - edit_posts - Controls whether objects of this post type can be edited.
* - edit_others_posts - Controls whether objects of this type owned by other users
* can be edited. If the post type does not support an author, then this will
* behave like edit_posts.
* - delete_posts - Controls whether objects of this post type can be deleted.
* - publish_posts - Controls publishing objects of this post type.
* - read_private_posts - Controls whether private objects can be read.
*
* These five primitive capabilities are checked in core in various locations.
* There are also six other primitive capabilities which are not referenced
* directly in core, except in map_meta_cap(), which takes the three aforementioned
* meta capabilities and translates them into one or more primitive capabilities
* that must then be checked against the user or role, depending on the context.
*
* - read - Controls whether objects of this post type can be read.
* - delete_private_posts - Controls whether private objects can be deleted.
* - delete_published_posts - Controls whether published objects can be deleted.
* - delete_others_posts - Controls whether objects owned by other users can be
* can be deleted. If the post type does not support an author, then this will
* behave like delete_posts.
* - edit_private_posts - Controls whether private objects can be edited.
* - edit_published_posts - Controls whether published objects can be edited.
*
* These additional capabilities are only used in map_meta_cap(). Thus, they are
* only assigned by default if the post type is registered with the 'map_meta_cap'
* argument set to true (default is false).
