*  Provides utilities to access points for clients.

*  Encapsulates database handling.

*  This class provides utility functions for clients that need some

*  specific information or parameters from (maybe more than one) AP.

*  It is provided for ease of use so clients do not have to work with

*  CApDataHandler's concept (one object-one Uid).
