Support for loading open file pointers / gzip file pointers

[GoogleCodeExporter]

Hi,

I recently had the need for loading gzipped arff files and added the following 
code to allow file objects (such as those returned by gzip.open) to be directly 
parsed.

Here is the patch for arff/__init__.py:

237,240d236
< # Responsibility for closing fobj is left to the caller
< def load_file_object(fobj):
<     for item in Reader(fobj):
<         yield item
244c240,242
<         load_file_object(fhand)

---
>         for item in Reader(fhand):
>             yield item
>

My above patch doesn't work on some versions of python. I therefore recommend 
the following patch, which just duplicates a bit of code:

237,240d236
< # Responsibility for closing fobj is left to the caller
< def load_file_object(fobj):
<     for item in Reader(fobj):
<         yield item
