FILE: CRefCneRadio.cpp
OVERVIEW: The CRefCneRadio class provides means to control an air
interface upon creation of its object. Some of the methods
such as bIsDataConnected, bIsConStateChanged, provide means to
find out the current connectivity state of the radio
DEPENDENCIES: The CRefCneRadio class is constructed for a unique air interface
denoted by its RAT type. Once constructed, all other methods
can be called on this object.
