//! # Bytestat
//!
//! Bytestat measure randomness of data. 
//! Data is readed from stdin.
//! The final score is between 0 and 100. 
//! Good quality random data should score 100 when rounded.
//! If the sample size if too small to be significant, the "~"" symbol is added as a prefix.
//! Example: ~68% is a bad score, but there is not enough data for the method to be precise.
//!
