log.getLevel()

log functions

// only outputs if logLevel === 'all'
log.info('Some interesting yet useless information')

// only outputs if logLevel === 'all'.
// output of first argument is green.
log.success('yay', 'only the first', 'argument was green')

log.error('ERROR:', 'error messsage')

// outputs if logLevel === 'warn' || 'all'
log.warn('WARN:', 'warn message')

// make a message greyed out
log.annotate('Annotate this message')

// return process.hrtime to use in log.timeTaken
const start = log.hrtime()

// get delta between one hrtime and another
const delta = log.hrtime(start)

// print the s, ms or ns since start
log.timeTaken(start, 'before', 'after')
