* The swap handler provides APIs and data structures for evaluating the swap requests.
* These APIs are registered as application callbacks and used by the PDStack middleware library.
* 
* <b>Features:</b>
* * Data role swap
* * Power role swap
* * Fast role swap
* * VConn swap

********************************************************************************
*
* The following steps describe the usage of the swap handler APIs.
*
* 1. Include swap.h to get access to all functions and other declarations.
*    \snippet swap_sut.c snippet_swap_include
*    \n
* 2. Initialize the swap functions to the application callback structure.
*    \snippet swap_sut.c snippet_swap_cbk_structure
*    \n
* 3. Register the application callback to the PdStack middleware library.
*    Refer to the \ref section_pmg_app_common_quick_start section.
