This is the executable for the ipKchat text client.  As it stands from
version 1.8 this is an undocumented feature and add on.  In general 
this should not be used.  But, if it has to be used it is the basis
from which the GUI version was constructed.  Very simple, this class
instantiates two threads, 'ClientFrom' to type the input to the screen
and 'ClientTo' to send the output to the server.
