   Purpose:    Call functions from Hubbot Script. Implementation of hbAPI derived
               class.

   Description:
               cltcontext.h contains the TextClientContext class which is derived from 
               the hbAPI class.

               We only redefine the Constructor/Destructor, the className() method.
               The Constructor of Controller registers the function we want to call
               from the Hubbot scripts. 

   Module:     cltcontext.cpp
