Independent start/end date selection

[meraj-ahmed]

As shown in the demo (http://luisfarzati.github.io/ng-bs-daterangepicker/), the start date and end date can be selected and re-selected independently of each other. I am unable to reproduce this functionality. My date range picker ends up behaving the same as bootstrap-datepicker, which only allows you to select the start date and end dates in that order (e.g., clicking a date a third time will reset the previous range selection and begin a new range selection). Does anyone know what I should do differently to make it behave the same as the demo?
