Add an example using the BoolCrit argument of CreateInputsCrit

Add an example using the BoolCrit argument of the CreateInputsCrit() function could be a good idea. The difference with the IndPeriod_Run argument of the CreateRunOptions() function is not very intuitive for users.

This is particularly interesting for calibration above or below a flow threshold, for certain months of the year only, etc.

We should put this example in a help page or a vignette.
