Detailed Description

An array of histogram bins.

This class overloads the array index operator[]. For an instance of bin_vec named binz, binz[i] will return the frequency value at index i.

The class constructor is passed a value for the number of bin_vec elements. It dynamically allocates an internal array.

The class destructor deallocates the internal array.

The start and end values for a given bin are referenced via the start and end functions.
