Detailed Description

A replacement type for ‘bool’ which does not allow automatic conversion to/from ‘int’ etc.

Doesn’t do fancy stuff like allow comparisons, but can use as the condition in ‘if’ statements, and supports automatic conversion to (but not from) bool.

Currently used in the SubSpectrum class to resolve overload ambiguities between int and bool arguments due to automatic conversions.
