Importing as Ext Flask Modules

Hy..

i could installed using:
* pip install flask-wysiwyg

But i cant import it:

I tryied using the example in readme:
* from flask-wysiwyg import WysiwygField
(it breaks in python compile)

And tryied using the .ext from flask:
* from flask.ext.wysiwyg import WysiwygField
( this case says that WysiwygField does not exists)

To fix it here is the pull request
