ok cool. i have a few setup issues but totally understand if you don't have the bandwidth to walk me through them. 1) do i need the api keys to get running locally -- do you have test keys I can use? 2) grunt starts with this warning "heatmap.js was not injected in your file." can i ignore? 3) i see this error repeatedly in console "Failed to open socket on port 5858, waiting 1000 ms before retrying" do i need to serve as root?
