Echo JS 0.11.0

I was actually just trying to make my dad's job easier, he does roofing and sometimes needs a quick and dirty roof map to show his guys where to look for leaks and such. Building have the detailed maps of the area. 

Also I was thinking that one day I can make it into something like http://www.roofcad.com/ with the added benefit of a database service for keeping track of previous leaks and repairs but honestly I haven't made any market research to see how viable the idea might be.
