This module provides common utility functions used in App::Grok.

Downloads a file from the web and returns the contents. Prints a progress bar (if Term::ProgressBar is installed) as while doing so. It takes two arguments, a title string and the url. Returns the downloaded content.

Creates (if necessary) and then returns the name of the directory where grok stores its data (e.g. ~/.grok).
