/**
 * The parent class for all Elgg Entities.
 *
 * An \ElggEntity is one of the basic data models in Elgg.  It is the primary
 * means of storing and retrieving data from the database.  An \ElggEntity
 * represents one row of the entities table.
 *
 * The \ElggEntity class handles CRUD operations for the entities table.
 * \ElggEntity should always be extended by another class to handle CRUD
 * operations on the type-specific table.
 *
 * \ElggEntity uses magic methods for get and set, so any property that isn't
 * declared will be assumed to be metadata and written to the database
 * as metadata on the object.  All children classes must declare which
 * properties are columns of the type table or they will be assumed
 * to be metadata.  See \ElggObject::initializeAttributes() for examples.
 *
 * Core supports 4 types of entities: \ElggObject, \ElggUser, \ElggGroup, and
 * \ElggSite.
 *
 * @tip Plugin authors will want to extend the \ElggObject class, not this class.
 *
 * @package    Elgg.Core
 * @subpackage DataModel.Entities
 *
 * @property       string $type           object, user, group, or site (read-only after save)
 * @property-write string $subtype        Further clarifies the nature of the entity (this should not be read)
 * @property-read  int    $guid           The unique identifier for this entity (read only)
 * @property       int    $owner_guid     The GUID of the owner of this entity (usually the creator)
 * @property       int    $container_guid The GUID of the entity containing this entity
 * @property       int    $access_id      Specifies the visibility level of this entity
 * @property       int    $time_created   A UNIX timestamp of when the entity was created
 * @property-read  int    $time_updated   A UNIX timestamp of when the entity was last updated (automatically updated on save)
 * @property-read  int    $last_action    A UNIX timestamp of when the entity was last acted upon
 * @property       string $enabled        Is this entity enabled ('yes' or 'no')
 *
 * Metadata (the above are attributes)
 * @property       string $location       A location of the entity
