    /* seedrandom originally from 
    * http://davidbau.com/encode/seedrandom.js
    *
    * seedrandom is basically a emitter of stringified bytes
    * deriving from a stream cipher algorithm (crypto bit/byte generator)  
    * seeded with/on the browsers crypto.randomValues implementation
    * 
    * the original uses RC4 as bit/byte-Emitter
    * this implementation uses Bernsteins Salsa20 instead
