Tutorial MD's are great, the issue here was that the level of JS knowledge for the students was so low that it meant they couldn't get as far as we would have liked with it.
Really not sure about this one, maybe run it one more time with slightly experience crowd to get some better feedback.
This needs to be introduced after the javascript introduction and ' for loop' perhaps a ' map' challenge.
We need an example of how to pass an array of co-ordinates to the google api.
