Sometimes you want to create a lib and have it work on it's own,
but you also want to use it with npmlog. This will help :)
npm i npmlog-stub
Now you can use the npm log functions in a stand alone lib:
var log = require('npmlog-stub');
log.info('This is a test');
It will write nothing, if npmlog is not also installed. If it's installed
it will be used.
