Right, the purpose of UIReloader is just to present a quick example to
demonstrate how this can be done. I should make that more explicit in the
comments.
@pwendell and I discussed this more offline. The proposal is to extract the
server logic from SparkUI, and treat it as a handler for an existing server.
This could be the server that holds the Master UI, for example. Further, we
need to figure out a way to pass the log directory of the SparkUI to the
external server, which should not be too complicated.
