// nacl_histogram provides an enum and defines a macro that uses definitions
// from histogram.h. Note that a histogram is an object that aggregates
// statistics, and can summarize them in various forms, including ASCII
// graphical, HTML, and numerically.
// nacl_histogram information is used to compare how many times a native
// client module has been loaded, compared to the number of chrome starts
// and number of new tabs created.
