'''Returns the objects linked to p_obj through this Ref field.
- If p_type is "objects", it returns the Appy wrappers;
- If p_type is "zobjects", it returns the Zope objects;
- If p_type is "uids", it returns UIDs of objects (= strings).
* If p_startNumber is None, it returns all referred objects.
* If p_startNumber is a number, it returns self.maxPerPage objects,
starting at p_startNumber.
If p_noListIfSingleObj is True, it returns the single reference as
an object and not as a list.
If p_someObjects is True, it returns an instance of SomeObjects
instead of returning a list of references.'''
