[HOT] HOT/HDM web rendering

Yohan can speak for himself if he's on his emails from Haiti, but I think I can answer some of these questions.

Yohan's been beavering away on this on github, https://github.com/hotosm/HDM-CartoCSS 
including making use of the 'issues' to guide his work, so I guess he'll welcome your suggestions (and pull requests!) there.

Good question Fran.  I don't he's making any promises about the availability and scalability of his umpa.fluv.io server  .  Stephanie was also suggesting it be hosted at a shorter more explicit URL (This is trivial for a web map, but this suggestion applies to the tiles themselves)

In general HOT would like to firm up some of the services we're using/dependent upon, hence this idea of having a sysadmin to install and oversee things: http://hot.openstreetmap.org/hot_tech_challenge_services_set_up_monitoring_and_administration    A tile server with this custom rendering could be such a "high availability" service. I think that would be a good idea. We wouldn't necessarily want to install mapnik & diff updating somewhere though, because we have a free Mapbox account, so that would be easiest. To be discussed.
