RF - move around some of the predict stuff
RF - shm fit should not have a prediction matrix
RF - minor optimization of predict
RF - move default_sphere into dipy.data
RF - get rid of csd_predict function
TST - improve tests for CSDModel.predict
BF: Use the short version to verify scipy version.

Otherwise, you might get these errors:

"ValueError: invalid version number '0.15.0.dev-12f8a6f'"

When running scipy from git.
TST - test gfa of masked areas in fits
BF - gfa should not return nan if all coefficients are zero
Make comment more clear

Revert "Support read-only numpy array."
DOC: References for the DTI ODF calculation.
BF: replaced non-ascii character in dipy.reconst.dti line 956
Update Cython download URL
RF: move script running code into own module

Refactor code to run scripts into own module.  In fact I'm using a
version I refactored for another project, to make it easier to use
across projects, but I think this makes the code easier to read and
support.
BF: workaround missing __package__ in Python 3.2

Python 3.2 does not set __package__; work around for now.
RF: change "below" to "above" for higher directory

I tend to think of directories nearer root as being 'down', it looks
more common to think of this as being 'up', change according to Ariel's
suggestion.
BF - Set parallel=False in reconst_csd example
BF - add multiprocessing support for froxen Windows executable
RF - putted all code under if __name__ == '__main__'
