* Haversine distance formula. | |

* This calculates the distance between geo coordinates in km<br> | |
* Algorithm: http://www.scribd.com/doc/2569355/Geo-Distance-Search-with-MySQL<br> | |
* Full calculation with Haversine formula is slow, so limit the whole distance to a rectangle, | |
* then calculate the distance. | |

* 1° of lat -> 111km (69 miles)<br> | |
* 1° of lon -> cos(lat)*111<br> |
