Declares the checkpoint handler class.

This class sets the signal to checkpoint based on the elapsed simulation time, and handles the signal if it is received. When handling the signal (via decideIfCheckpointingThisStep()), it is deciding whether a checkpoint should be saved at the current step. This can be due to a received signal, or if the current simulation step is the last. This information can be queried via the isCheckpointingStep() function.

The setting and handling is implemented in private functions. They are only called if a respective boolean is true. For the trivial case of no checkpointing (or no checkpoint signal setting on any other rank than main), the translation unit of the calling function is therefore never left. In the future, this will be achieved by adding (or not adding) handlers / setters to the task graph.
