Con y sin println

con-y-sin-println.scala

// The t function takes times and puts data points in an arraybuffer.
// I use that data to compute mean, stddev, variance ...
//
// The Walker just recursively walks a jsoup document feeding the elements to the parser
// or the parsers it returns and accumulating the new ast nodes. 
// Lot's of work for the GC
// 
// On one run there are two printlns, on the other none.
//

// Run this twice with and without println, see below for numbers.
