get/set the verbosity level.

The verbosity level filters messages that are output
to the console. Only messages tagged with a verbosity
less-than-or-equal-to the class verbosity are output.

This does not affect output to non-console devices
such as files or remote sockets.

verbosity():    returns the current level
verbosity(<N>): sets the verbosity to <N>
