Summary: replace __slots__ with addmembers

Initial Comment:
This  patch replaces the __slots__ syntax in the
following example:

>>> class B(object):
	"""class B's docstring
	"""
        __slots__ = ['a','b','c','d']


The new syntax includes support for docstrings, default
values, and optional typechecking (using isinstance).  

>>> class B(object):
	"""class B's docstring
	"""
        a = addmember(types=int, default=56, doc="a
docstring")
        b = addmember(types=int, doc="b's docstring")
        c = addmember(types=(int,float), default=5.0,
doc="c docstring")
        d = addmember(types=(str,float), default="ham",
doc="d docstring")
       
>>> b = B()
>>> b.a
56
>>> b.d
'ham'
>>> b.b
Traceback (most recent call last):
  File "<pyshell#8>", line 1, in ?
    b.b
TypeError: The value of B.b is of type 'type'. This is
not one of the defined types

The addmembers.txt file in the attachment describes the
patch in more detail.
