On-line documentation is generated daily using current repository code. 
I seems that you are using some of the previous versions, and that's the 
reason of your problems.
Six weeks ago changeset:
http://www.fenics.org/hg/dolfin?cs=75bc001441e8
replaced enum by strings.

Rectangle class is used in several demos:
demo/mesh/built-in/python/demo.py
demo/mesh/submesh/cpp/main.cpp
demo/pde/waveguide/cpp/main.cpp
Take a look, it should help at the beginning.
