1.4.2

• Use periodSettings from the dataStore to determine which periods to display for each of the dataSetGroups (e.g. workflows). https://github.com/pepfar-datim/Global/issues/2253
• General refactoring
• Adds new header-bar that was introduced with DHIS2 2.24

The dataStore period settings should have the following format

            "end": "Fri Apr 14 2017 21:00:00 GMT+0200"
        }
    },
