OGR Features don't have a 'keys()', 'items()' interface

[crschmidt]

It would be nice to be able to do:

for key, value in feature.items():

print key, value

in Python.

for key in feature.keys() would be handy as well.

If neither of these is possible, a method to return a list of the keys which can be passed to getattr:

getattr(feature, key)

ould be good.
