// ==================================== Coordinate Interception ====================================

// Below, I intercept the API call to Google Street view and view the result before it reaches the client.
// Then I simply do some regex over the response string to find the coordinates, which Google gave to us in the response data
// I then update a global variable above, with the correct coordinates, each time we receive a response from Google.
// This needs further testing - but initial tests look promising
