/**
* @example LogicBlock.cpp
*
* @brief LogicBlock.cpp shows how to use logic blocks to detect missing
* triggers and refire. It relies on information provided in the
* Acquisition and Trigger examples.
*
* A logic block is a collection of combinatorial logic and latches that allows
* users to create new, custom signals inside the camera. These custom signals
* can be used by the camera (for example to trigger exposure) or sent out to
* integrate with external systems.
*
* Logic Block functionality is only available for BFS and Oryx Cameras.
* For details on logic blocks and how this example works, see our kb article,
* "Using Logic Blocks with Blackfly S and Oryx";
