Instructs RestKit to automatically connect a relationship of the object being mapped by looking up
the related object by primary key.
Instructs RestKit to connect a relationship of the object being mapped to the
appropriate target object(s). It does this by using the value of the object's
fromKeyPath attribute to query instances of the target entity that have the
same value in their toKeyPath attribute.
Note that connectRelationship runs *after* an object's attributes have been
mapped and is dependent upon the results of those mappings. Also, connectRelationship
will never create a new object - it simply looks up existing objects. In effect,
connectRelationship allows foreign key relationships between managed objects
to be automatically maintained from the server to the underlying Core Data object graph.
For example, given a Project object associated with a User, where the 'user' relationship is
specified by a userID property on the managed object:
