Rewrote drawing to support rounded corners for any shape, not just to create circles.
Updated annotationViews to new dimensions for the new drawRect method. Also removed unnecessary custom draw string method now that we use attributed strings. Instead a dictionary for the stringAttrs is defined in the interface.
drawInRect withAttributes is nonexistent on ios6, instead use alternative (inferior) solution on versions below iOS7.
Fixed bug that would make mapview cover arrivalsVC.
