Detailed Description

Changes a verbosity level for the instance variable's lifetime.

Create a LevelChange variable on the stack to temporarily (e.g. for a single method) increase the quantity of information logged.

Typically used to propagate the locally used logger's level (e.g. DEBUG or TRACE) to another named (e.g. the name of the class of the method invoked next) logger.

The LevelChange variable does not need to be removed from the code (e.g. for a release build) as it has no impact when the local and other logger point to the same level (e.g. null_ptr, implying their level is inherited).
