 *  The user has the option to select 4 different types of debugging levels,

 *  The critical level will show only those messages

 *  allocation errors. The remaining three levels are just for debugging 
 *  purposes.  Packet level will display all the incoming and outgoing 
 *  packets that are flowing between the control point and the device. 
 *  Info Level displays the other important operational information 
 *  regarding the working of the library. If the user selects All, 
 *  then the library displays all the debugging information that it has.
