Title: Updated comment that gave incorrect information

Changed comment on line 56: "// Call vector heading function to get direction (note that pointing **up** is a heading of 0) and rotate"
To: "// Call vector heading function to get direction (note that pointing **to the right** is a heading of 0) and rotate".

This confused me greatly until I realised the comment is simply wrong!
