This directory contains the Main entry point to the Sample applications as well
as functions that are common to applications using the SDK. There is usually no
need to edit the file CommonMain.c. The Makefile creates a libCommonMain.a file
in the library directory used by applcation programs of the SDK.

It requires 2 entry points to the application specific tasks 

- AppRegisterCallBack() : The application registers its own callback 
                          function using this.
- Run_App() : The main core of the application.
