Summary: genpy : _NewEnum for dynamic collections

Initial Comment:
In a previous thread on comp.lang.python a request was 
made to have _NewEnum called for each for blocks and 
not only once and then cached in the python proxy 
class generated by genpy:

Indeed the _NewEnum normally gives an iterator that 
iterates on a copy of the collection data.
This is the desired behaviour when iterating on a for 
block but next time if the collection is updated, it is 
desired to iterate on the latest copy so we need to get 
a new iterator.

I made a change in genpy to create the __iter__ method 
that is called each time an iterator is requested before 
the __getitem__ is called.
I also added in win32com.client.util the WrapIter 
function with its associated class.

It seems to work well for my collection. Hope it may help 
someone. The modified files are attached
