// This provides some helper methods for building and rendering an
// internal html page.  The flow is as follows:
// - instantiate a builder given a webframe that we're going to render content
//   into
// - load the template html and load the jstemplate javascript into the frame
// - given a json data object, run the jstemplate javascript which fills in
//   template values
