Comment (by dhuard):

 The patch makes sure that:
  - outliers are not counted.
  - normalization is done correctly, that is, sum(hist*diff(bins))==1.

 Also, I added support for weights for good measure.

 It breaks the current behavior in the following ways:
  - returns the bin edges (nbins+1) instead of the left bin edges.
  - upper outliers are not put in the closest bin.
