Ham::Reference::Qsignals - A quick reference for Q Signals.

 my $q = new Ham::Reference::Qsignals;

 # use the get() function to get a single meaning for a particular Q signal

 print $q->get('qrp');
 print "\n";

 # use a hash reference to get all Q signals at once
 # the following will display all signals and meanings

 my $hashref = $q->get_hashref();

 Usage    : my $q = Ham::Reference::Qsignals->new();
 Function : creates a new Ham::Reference::Qsignals object
 Returns  : A Ham::Reference::Qsignals object
 Args     : an anonymous hash:
            key         required?   value
            -------     ---------   -----
            signal_set  no          select the set of Q signals
                                    the only set for now, and the default set
                                    is arrl

 Usage    : my $description = $q->get( 'qrp' );
 Function : gets a single meaning for a given Q signal
 Returns  : a string
 Args     : you can get a full list of Q signals by accessing the keys of
            of the hashref returned by get_hashref() function
            (see the synopsis for example)

 Usage    : my $hashref = $q->get_hashref();
 Function : get all q signals
 Returns  : a hash reference
 Args     : n/a
