// This generator yields everything from ~2% real english words over ~75% english sounding words and ~10% strange words to ~13% unreadable crap.
// Try it out. It was created as a tradeoff between size and good results, if you need something better, well do it yourself.
// If you drop me a line I might also be able to dig out the initial python source for this thing which was more powerful and worked
// with more than just 1grams and 10 followers.
// If you think you have an improvement, write a comment.

// list of characters with their followers' corresponding accumulated propabilities
// accumulated probabilities are usable as keys and work great with Math.random()

Hey, I appreciate the reply! I actually ended up figuring out and doing basically what you describe.
