HistogramBins

Bins for a histogram. These can be implicitly constructed from:

<pre> x : HistogramBins = 10 // 10 dynamically determined histogram bins x : HistogramBins = Array(1.0,2.0,3.2) // five buckets wit the given splits x : HistogramBins = (0,100,10) // ten bins evenly dividing 0 to 100. </pre>
