To make it start from Sunday we need to do below modifications in library project

1 --> In WeekCalendar class go to getWeekDayNames() method. Here keep daysName.remove(0); and remove/comment daysName.add(daysName.remove(0));.

2 --> In WeekFragment class go to init() method. Here set midDate to WEDNESDAY like below
if (midDate != null) { midDate = midDate.withDayOfWeek(DateTimeConstants.WEDNESDAY); }
