// Interval //
// //
// Interval definition, continuous and discrete //
// //
// Interval(min,max) : a continous interval [min,max] //
// Interval(min,max,n): a "discrete interval" [min,max], i.e the n numbers: //
// min, min+step, min+2*step,...., min+(n-1)*step, min+n*step=max //
// e.g.: Interval(1,5,5)=1,2,3,4,5 //
// Interval(.5,1.,6)= .5, .6., .7, .8, .9, 1.0 //
// //
// Note: **bin** counting starts from ZERO unlike in ROOT histograms //
// //
// Example: Interval(.5,1.,6) //
// //
// [ min max ] //
// ------------------------------------------------------------ //

// .5 .6 .7 .8 .9 1.0 //
