Simple wrapper around console.log which prepends a duration at the start.
var clog = require('whir-clog');
clog('hi'); // 0.022s - hi
// can bind it just like console log too
var boundClog = clog.bind(null, 'other');
boundClog('thing'); // 0.032s - other thing
##todo
- adapt timestring depending on how long it has been running
