Revision: 1373
          http://svn.sourceforge.net/epydoc/?rev=1373&view=rev
Author:   dvarrazzo

Log Message:
-----------
- Allow parameter-related fields in a class docstring: use them to extend the
  matching __init__ docstring.
- Enforce docstring parsing in dotted name order to ensure class docstring
  have already been parsed at __init__ docstring parsing time.
- "type" fields are used to specify both class/instance variables types and
  constructor arguments types. In case a type is expressed in both class and
  __init__ docstring, the latter wins (e.g. the __init__ may receive an arg,
  parse it and store it in the instance state with the same name but different
  type)
