Service to detect IE

[mitogh]

Steps to reproduce and a minimal demo of the problem

Sometimes is useful to detect in directives if we are under a IE version to generate fallback solutions

Current behavior

Nothing is present

Expected/desired behavior

I think if we add a new service that we can use consistency might be useful, here is the code of the service implemented in other project.

import angular from 'angular';

angular
  .module('app')
  .factory('ie', ie);

function ie() {
  return {
    isActive: isActive,
    isEdge: isEdge,
    is11: isIE11,
    isOld: isOldVersion
  };
  function isActive(){
    return isEdge() || isIE11() || isOldVersion();
  }
  function isEdge(){
    return /Edge/.test(navigator.userAgent);
  }
  function isIE11(){
    return /Trident.*rv[ :]*11./.test(navigator.userAgent);
  }
  function isOldVersion(){
    return /MSIE/.test(navigator.appVersion);
  }
}
