Digital triggered continuous offline storage

Note

Steps:
1.Create task. VkDaqCreateTask
2.Create analog output channel VkDaqCreateAIAccelChan
3.Set sampling clock VkDaqCfgSampClkTiming
4.Set digital trigger VkDaqCfgDigEdgeRefTrig
5.Start offline task VkDaqStartOfflineTask
6.Stop task VkDaqStopTask
7.Clear task VkDaqClearTask
