/**
* @class   GoWebScanSyncTask
* @extends kObject
* @ingroup GoWebScanSdk-Control
* @brief   Represents a task to match profile, vision, and tracheid tiles by Y-position and
*          monitor for time and distance coherency violations.
*          
*          A GoWebScanSyncTask object receives tiles corresponding to the profile, presence, 
*          vision, and tracheid data from all individual cameras. Tiles are matched by 
*          Y-position, and then emitted in lists corresponding to the profile, presence, 
*          vision, and tracheid data in the top and/or bottom groups. The task receives
*          GoWebScanProfileTileMsg, GoWebScanVisionTileMsg, and GoWebScanTracheidTileMsg
*          objects and outputs GoWebScanTileListMsg objects for each data type. A GoWebScanSyncTask 
*          instance delegates most of its work to the GoWebScanTileCombiner algorithm. 
*          Incoming messages are passed directly to the GoWebScanTileCombiner instance, and 
*          outputs from the GoWebScanTileCombiner are immediately emitted as outputs from the 
*          GoWebScanSyncTask.
