For a given edit area, the histogram will list the number of occurrences of each grid value. Suppose, for example, we are sampling a MaxT grid over a small edit area of 30 points. You might have a list of pairs:
(10,70), (15, 71), (5, 73)
indicating that 10 grid points had a value of 70 degrees, 15 points had a value of 71 degrees, and 5 grid point had a value of 73 degrees.
The Sampler code is written in C++ for maximum performance.
