I/O Plugin infrastructure + wx/qt plugins

[Stéfan van der Walt]

Hi all,

Chris and I have been working towards a more complete plugin framework
this afternoon.  Please have a look at

http://github.com/stefanv/scikits.image

in the `io` branch to see what's been done so far.  You may try the
new qt or wx image display plugins as follows:

import scikits.image.io as io
import numpy as np

io.load_plugin('qt')  # or 'wx'
io.imshow(np.random.random((200, 200))

All the plugins available may be queried with

io.plugins()

Regards
Stéfan
