-// This class implements a simple histogram.
-
-// A histogram summarizes a series of "measurements", each of which is
-// assumed (required in this implementation) to have an outcome that is a
-// non-negative integer.  The histogram efficiently maps measurement outcomes
-// to the number of measurements had that outcome.
-
-// To print the results, invoke print() on your Histogram*.
-
-// Note: there is already an existing "Histogram" class, in file
-// histogram.{hpp,cpp}, but to my mind that's not a histogram, it's a table
-// mapping strings to counts.  To be a histogram (IMHO) it needs to map
-// numbers (in fact, integers) to number of occurrences of that number.
-
-// ysr: (i am not sure i agree with the above note.) i suspect we want to have a
-// histogram template that will map an arbitrary type (with a defined order
-// relation) to a count.
