\author Jasem Mutlaq
\example tutorial_client.cpp
Construct a basic INDI client that demonstrates INDI::Client capabilities. This client must be used with tutorial_three device "Simple CCD".
To run the example, you must first run tutorial_three:
\code indiserver tutorial_three \endcode
Then in another terminal, run the client:
\code tutorial_client \endcode
The client will connect to the CCD driver and attempts to change the CCD temperature.
