When we initialize a new PySimLogger, we always call the setup method
first and then use the set_verbose and set_level method to configure
the initial log level and the initial log verbosity. However, we
initialize the PySimLogger in all our programs the same way and we
end up with the same boilerplate code every time. Let's add a keyword
parameter to the setup method where we can pass our opts.verbose (bool)
parameter so that the setup method can do the work for the main program.
In case the caller wants a different default configuration he still can
call set_verbose and set_level methods as needed.
