Summary: Creation of struct_seq types

Initial Comment:
It would be really nice to be able to create structure
sequence types from within Python.  MvL suggested:
-------------------
... I think all you need to do is to expose
PyStructSequence_InitType. I would recommend an
interface like

struct_seq(name, doc, n_in_sequence, (fields))

where fields is a list of (name,doc) tuples. You will
need to temporarily allocate a PyStructSequence_Field
array of len(fields)+1 elements, and put the
PyStructSequence_Desc on the stack. You will also need
to dynamically allocate a PyTypeObject which you return.

I would put this into the new module.
-------------------
Assigned to me since I actually wanted to create these
things.

Uploaded patch 980098 which implements this functionality as 
a separate module.

As part of this, struct_seq types should be made subclassable.
