* Uses the GeoIP PECL module to get a visitor's location based on their IP address.

* region code, city name, area code, latitude, longitude and postal code of the visitor.
*
* Alternatively, if only the country database can be detected, only the country code
* will be returned.
*
* The GeoIP PECL module will detect the following filenames:
* - GeoIP.dat
* - GeoIPCity.dat
* - GeoIPISP.dat
* - GeoIPOrg.dat
*
* Note how GeoLiteCity.dat, the name for the GeoLite city database, is not detected
* by the PECL module.
