SimpleITK IO Plugin

This adds support for SimpleITK (http://simpleitk.org/) as an IO plugin to read and write a large number of file formats including many formats encountered in medical imaging.  It should be tested against an install from SimpleITK 0.6rc1 or better to incorporate an egg from @blowekamp, eggs of which can currently be installed after a manual download from Sourceforge:

  http://sourceforge.net/projects/simpleitk/files/SimpleITK/0.6.rc1/Python/

easy_install will be available after the final release of 0.6.0.
