This class is the main class that handles MIP handover in a 
CDMA2000 network. It is written as an active object.
It is triggered by one of two things
1) a PPPLinkDown event or
2) an ETEL notification that we have changed Zone

When either of these two events come in it triggers a timer.
If the timer runs out before the other  event takes place a normal
Reconnect dialog box is shown. But, if the other event takes place 
before the timer runs out, we will restart the connection without 
user intervention.
Lifetime of the object is as long as its owner.
