RGSpace: get_distance_array() returns incorrect results for odd lengths
With current master, try the following code in ipython:
from nifty import *
s_space = RGSpace([3])
s_space.get_distance_array('not')
The result I get is
<distributed_data_object>
array([ 0.33333333, 0.33333333, 0. ])
However, I would rather expect something like
array([0., 0.33333333, 0.33333333 ])
