* Google Maps Tutorial
* Txt2Java pCode Generated File
* Version 1.0.1.4
* B&P Software 2011
*
* This requires the Google API (Android 2.1)
* The mapping requires the correct API key in main.xml (B&P's won't work for other compilers)
* Uses the direction service to draw a blue line between the endpoints of the direction steps
* Stores the written directions also
