Numpy: use bins with infinite range

The function numpy.histogram() happily accepts infinite values in the bins argument:

numpy.histogram(my_values, bins=numpy.r_[-numpy.inf, my_bins, numpy.inf])

Alternatively, you could use a combination of numpy.searchsorted() and numpy.bincount(), though I don't see much advantage to that approach.

You can specify numpy.inf as the upper and -numpy.inf as the lower bin limits.
