Shiny app

[gluc]

A little shiny app that serves as a GUI for the package. Similar to http://ipub.com/apps/ahp for the ahp package at http://github.com/gluc/ahp package.
Basic workflow:

1. Load file
2. Display tree using http://github.com/renkun/formattable with color codes or http://github.com/timelyportfolio/listviewer
3. Add filters to, e.g. display only what uses more than 80% of the time

If you agree, I'll make a proposal and pull request

Good idea.
