/**
* DOCINFO
*
* DocInfo is a JS layer on top of Cinnamon's DocSystem (which is written in C).
*
* The advantages of using DocInfo (rather than Gtk.RecentManager) are:
*
* - Results are limited to 20 (with RecentManager you can get a huge number of results)
* - Results are sorted by timestamp (they're not sorted by RecentManager)
* - Sorting and clamping of the results is done in C and only the 20 most recent results are stored in memory
* - The "changed" signal sent by DocSystem is delayed via idle_timeout, so your applet doesn't rebuild immediately when Gtk.RecentManager sends its signal (which could potentially reduce the speed at which apps are launched)
* - DocInfo provides decoded URIs and the ability to quickly create the icon so your applet doesn't need to do that itself.
