/*
* Whisper.View
*
* This is the base for most of our views. The Backbone view is extended
* with some conveniences:
*
* 1. Pre-parses all our mustache templates for performance.
* https://github.com/janl/mustache.js#pre-parsing-and-caching-templates
*
* 2. Defines a default definition for render() which allows sub-classes
* to simply specify a templateName and renderAttributes which are plugged
* into Mustache.render
*
* 3. Makes all the templates available for rendering as partials.
* https://github.com/janl/mustache.js#partials
*
* 4. Provides some common functionality, e.g. confirmation dialog
*
