/* 
  Installation: npm install linewise
  Usage:
  
  cat urls.json | node extract.js > urls.txt

  Assuming urls.json contains lines with zero or more urls per line, this will 
  extract all the urls and produce a file with one url per line.

// this function can get the full stack trace, however, it's usefulness is 
// somewhat limited by the fact that Chrome Dev tools can only display full
// urls that are passed as the first argument as a string. That means that 
// every log line is preceded by a massively ugly URL block that works as 
// a link but this is only mildly useful. There is no way to get the dev 
// tools to linkify shorter URLs - if that were possible, then this 
// might be a usable solution from a UI perspective
