Trying to create a new version of the map functions seen here: http://www.daftlogic.com/projects-google-maps-distance-calculator.htm but using the v3 api.

So far I am able to set markers on click and can draw the geodesic polyline. The issues I am currently running into are:

• Updating the poly-line on marker drag
• I'm pretty sure I have to put each marker in an array and do a for loop so that I can keep clicking and adding points that will add to the total distance.
• Properly displaying distance.

I have created a jsfiddle: http://jsfiddle.net/wyZyS/

EDIT: I realize I have nothing calling the "update" function. I am trying to create the array for each marker currently. The calculation you see is converting meters to nautical miles.
