Should be fully working with no bugs... Tried making the bus stops opaque (probably need to tune it more). So far, to make the stops appear, make sure to zoom into level 15 (slightly more than starting). Added TODO to easily add getPredictions. The most efficient way of displaying bus times is through the Google Maps way of looking at time...
