+//! \brief Basic debugging class to print out f's in a certain area of the domain
+//!
+//! Basic debugging class. Needs to be directly added in UpdateGrid (could potentially also be added as a proper Probe in the future)
+//! How to use: Define a part of the domain via min/max x, y, and z. The DistributionDebugInspector will print out all f's in that area.
