Detailed Description
a trash can for logging; throws away all entries.
Provides a logger that throws away all of the strings that are logged to it. This is useful when an interface requires a base_logger but one does not wish to generate an output file. This object is similar to /dev/null in Unix (or Linux) and to nul: in Win32.
