Update DSLCalendarMonthView.m

even when dates were equal it says not.. 
so with this. it work fine. 

With to changes i made now you can select a range of dates


NSDateComponents *startDateComps = [[NSCalendar currentCalendar] components:NSCalendarUnitDay | NSCalendarUnitMonth | NSCalendarUnitYear fromDate:_checkIn];
;
    
    NSDateComponents *endDateComps =  [[NSCalendar currentCalendar] components:NSCalendarUnitDay | NSCalendarUnitMonth | NSCalendarUnitYear fromDate:_checkOut];
    
    DSLCalendarRange *newRange=[[DSLCalendarRange alloc] initWithStartDay:startDateComps endDay:endDateComps];

    
    [self.calendarView setSelectedRange:newRange];
