  4.  * Yet another OpenGeo class
  5.  * version 0.1

  12.  * This class uses the openGEO-Database
  13.  * and supports Germany, Austria and Switzerland
  14.  * (i didn't need more)
  15.  * so feel free to add more.
  16.  * 
  17.  * For better performance I used a selfwritten filecache.
  18.  * I commented this lines out, so for now everytime the database gets requested.
  19.  * This produces a unnecessary load on your db-machine.
  20.  * 
  21.  * I'm using ADOdb for databasehandling, so if you want to use something different,
  22.  * you have to implement your own handling. ($this->getDB())
  23.  * 
  24.  * example:
  25.  * 
  26.  * $oOpenGeo = new OpenGeo();
  27.  * $oOpenGeo->setCountry('de');
  28.  * $oOpenGeo->getProvinceByZipCode(20539);
  29.  * returns:  
  30.  * 	   array(
  31.  * 			[loc_id] => 114
  32.  * 			[text_val] => Hamburg
  33.  *		)
