Issue source: rangle/redux-beacon#147

[leecade]

Discarded if console.group not exist? shall we replace with console.log

HOW ABOUT

if (!console.group) {
  let groups = []
  let hr = '-'.repeat(80)
  console.group = function logGroupStart(label) {
    groups.push(label)
    console.log('%c \nBEGIN GROUP: %c', hr, label)
  }
  console.groupEnd = function logGroupEnd() {
    console.log('END GROUP: %c\n%c', groups.pop(), hr)
  }
}
