48beade4 25/// \class AliMUONLogger
26///
27/// A logger that keeps track of the number of times a message appeared.
28///
29/// Typically used to print all messages to screen at once, e.g. in the
30/// dtor of a worker class.
31///
32/// For instance, it is used in AliMUONDigitizerV3, to note which channels
33/// are disabled, and this information is printed in a condensed form
34/// only once when DigitizerV3 is destroyed.
