## mustache_xpath_partials.js
/*
 * Q: What is this?
 * A: A sample file that uses mustache to render a single html tmeplate (including partials) on the serverside but keeps those partials intact so that they can be used by the client-side as well (ie. browser)
 *
 * Q: How is this useful?
 * A: To you, I have little idea. I'm doing this because I want to be able to fully render a page on the server and then refresh parts of it on the client, while reusing the widget presentation code. As the widget code is in the file, I just have to bring in mustache.js, fetch new data, and have it render the parts I need to update. And I'd like to keep it all in a single file also.
 *
 * Q: Isn't that template code broken?
 * A: Yes. I'll come back to it as I plan to patch Mu to support xpath partials natively.
