/**This is a sample/reference derivation of the connection provider factory.

Each such derivation should be able to produce a specific type of connection providers,

where the type usually denotes a particular technology (e.g.: IP, UMTS, SIP).

A connection provider factory is also responsible for handling selection,

i.e.: given or having access to all sorts of input (connection preferences, policies, 

bearer availablity) the factory should be able to select the provider on the given 

level and select the provider type on the level below.
