///
/// A logger that keeps track of the number of times a message appeared.
///
/// Typically used to print all messages to screen at once, e.g. in the
/// dtor of a worker class.
///
/// For instance, it is used in AliMUONDigitizerV3, to note which channels
/// are disabled, and this information is printed in a condensed form
/// only once when DigitizerV3 is destroyed.
