histogram (
        inarray,
        numbins=10,
        defaultlimits=None,
        )

Purpose: Returns (i) an array of histogram bin counts, (ii) the smallest value of the histogram binning, and (iii) the bin width (the last 2 are not necessarily integers). Default number of bins is 10. Defaultlimits can be None (the routine picks bins spanning all the numbers in the inarray) or a 2-sequence (lowerlimit, upperlimit). Returns all of the following: array of bin values, lowerreallimit, binsize, extrapoints. This code was adapted from stats.py, which is under the GNU GPl.
