This function outputs the message, if the log level is set to 'verbose'
or 'debug' for the current area of Fuego test execution. This function
should be used to output additional information that might be helpful for
the user to see about the test execution. These messages, however, do

See FUEGO_LOGLEVELS to see how the log level may be set.
Any shell variable can be output as part of the message.
