30// Interval //
31// //
32// Interval definition, continuous and discrete //
33// //
34// Interval(min,max) : a continous interval [min,max] //
35// Interval(min,max,n): a "discrete interval" [min,max], i.e the n numbers: //
36// min, min+step, min+2*step,...., min+(n-1)*step, min+n*step=max //
37// e.g.: Interval(1,5,5)=1,2,3,4,5 //
38// Interval(.5,1.,6)= .5, .6., .7, .8, .9, 1.0 //
39// //
40// Note: **bin** counting starts from ZERO unlike in ROOT histograms //
41// //
42// Example: Interval(.5,1.,6) //
43// //
44// [ min max ] //
