Changelog and versioning

[ryzy]

Hi,

Any plans for adding CHANGELOG.md to the repo? Would be useful.

BTW yarn info shows the following versions:

$ yarn info ng-daterangepicker
yarn info v0.23.2
{ name: 'ng-daterangepicker',
  description: 'AngularJS Daterangepicker',
  'dist-tags': { latest: '0.2.0' },
  versions: 
   [ '0.1.0',
     '0.1.1',
     '0.1.2',
     '0.2.0',
     '0.9.0' ],
  maintainers: 
   [ { name: 'jkuri',
       email: 'jkuri88@gmail.com' } ],
  time: 
   { modified: '2017-03-28T21:42:57.378Z',
     created: '2015-09-20T11:27:44.293Z',
     '0.9.0': '2015-09-20T11:27:44.293Z',
     '0.1.0': '2017-03-10T00:05:01.722Z',
     '0.1.1': '2017-03-12T19:42:43.737Z',
     '0.1.2': '2017-03-15T20:01:07.561Z',
     '0.2.0': '2017-03-28T21:42:57.378Z' },

Is the 0.9.0 the latest one? Bit weird, as it's apparently released in 2015, the 0.2.0 seems to be the latest one.
