The dolfin reference documentation regularly does not provide sufficient information for even basic use

Registered by Martin Sandve Alnæs

In many cases the python docstring only shows "*args" and no description of the arguments, and the reference documentation is no better. One example was Cylinder (now fixed):

"""
This class describes a 3D cylinder which can be used to build
geometries using Constructive Solid Geometry (CSG). A cylinder
is here just a special case of a cone.
Constructor information:
 Definition:Cylinder(self, *args)
"""
Where the programmers reference was no more useful.

But this is far from the only case. Shouldn't the programmers reference at least show argument names and types automatically?
