TPositionAreaExtendedInfo is a specialised area class and provides detailed

information about the match between the current network information and the network

information related to a known position.

In the future the class may be extended to provide information about a match between

other available location information (e.g. WiFi MAC address).

In order to provide a user with simplified area information, the match between

the two network information should be translated into a area information supported

by the TPositionAreaInfo type.

Please note that the conversion of the Cell Id match assumes the worst case scenario, where cells

are big (e.g. tens of km radius). In centres of big cities the cell sizes are normally much smaller,

taking the area down to the District or even Street level.
