title: how to check if your latitude and longitude are inside a circle?
body: <p>I am new to the Google Maps API and also mobile development through Phonegap(JavaScript). I am trying to use the current geoLocation obtained through phonegap and use it to determined if that location lies within a circle. Can anyone provide an example of how to perform this? A link to a thread that dealt with this would be useful as well. </p>
  
  <p>Thanks!</p>
