Deprecation warning in newer versions of scipy, because scipy.misc is going away

[arokem]

Warnings of this sort:

/home/travis/build/arokem/dipy/venv/lib/python3.5/site-packages/dipy/reconst/tests/test_mapmri.py:29: DeprecationWarning: `factorial` is deprecated!
Importing `factorial` from scipy.misc is deprecated in scipy 1.0.0. Use `scipy.special.factorial` instead.
  f = np.sqrt(2) * factorial(n) / float(((gamma(1 + n / 2.0)) *

Should be an easy fix to introduce a conditional import wherever we are importing factorial
