command line statistics

Feed in statistics on standard input and see number of samples, average, minimum, 1st quartile, median, 3rd quartile and maximum. Input can be prefixed with a common string, only the last word needs to be a number value. Statistics will be computed for each run of lines with equal prefixes.

Some statistics about the byte length of the first 10,000 words in the dictionary:
