/**
 * A Contact represents a single person or logical entity as perceived by the user.  The information
 * about a contact can come from multiple data sources, which are each represented by a RawContact
 * object.  Thus, a Contact is associated with a collection of RawContact objects.
 *
 * The aggregation of raw contacts into a single contact is performed automatically, and it is
 * also possible for users to manually split and join raw contacts into various contacts.
 *
 * Only the {@link ContactLoader} class can create a Contact object with various flags to allow
 * partial loading of contact data.  Thus, an instance of this class should be treated as
 * a read-only object.
