@antony Allow neater logging using SF

Include sf for powerful logging functionality for log/error/warn, rather than

bosco.log('Event '+event.name+' occurred  at'+event.time+' with code '+event.code+'!');

you can alternately do:

bosco.log('Event {name} occurred at {time} with code {code}', event);

as well as a load of other things:
