[super] Ability to load your own functions

[rufuspollock]

Should be able to specify new script libraries you can load.

This would address (or support) a lot of other issues including #68 (geocode scripting functions) and be a massive feature ...

I'm wondering if we could take inspiration from @maxogden's https://github.com/maxogden/requirebin plus browserify generally. As I understand requirebin it uses https://github.com/maxogden/browser-module-sandbox to run the actual user script. That in turn works roughly like this:

• Take the script and extract required modules using detective

• Use browserify-cdn to grab all of those modules and then call downloadedModules (if not already cached)

  request({method: "POST", body: body, url: self.cdn + '/multi', json: true}, downloadedModules)

• downloadedModules does some caching and then builds the iframe

Questions I have:

• Can you use browserify stuff in a web worker (I think so)
• How do we auto-insert the deps into the web worker at run time? (Or we could just dump the entire script code into the web worker and eval along with everything else!)

@maxogden re previous comment - any idea on the last set of questions? In particular, I take it one can do on the fly browserify-ication in the browser (and hence potentially in a web worker ...)
