title: How to select multiple event date in MaterialCalenderView
body: <p>I am using <a href="https://github.com/prolificinteractive/material-calendarview" rel="nofollow noreferrer">MaterialCalendarView</a> library, I want to select events dates problematically (no to be select by user in run time) which will  be multiple, After reading the documentation i saw four cases.</p>
  
  <ol>
  <li>SELECTION_MODE_NONE</li>
  <li>SELECTION_MODE_SINGLE</li>
  <li>SELECTION_MODE_RANGE </li>
  <li>SELECTION_MODE_MULTIPLE</li>
  </ol>
  
  <p>I used SELECTION_MODE_NONE as i don't want user to select date.
  I tried this but it doesn't show  me selected days which i passed.</p>
  
  <pre><code>private MaterialCalendarView materialCalendarView;
  materialCalendarView = view.findViewById(R.id.newCal);
   Calendar calendar = Calendar.getInstance();
      calendar.set(2017, 12, 1);
      calendar.set(2017, 12, 7);
      calendar.set(2017, 12, 8);
      calendar.set(2017, 12, 9);
      calendar.set(2017, 12, 10);
  
  
      materialCalendarView.addDecorator(new CurrentDayDecatator(getActivity()));
      materialCalendarView.setDateSelected(calendar, true);
      materialCalendarView.setSelectionMode(MaterialCalendarView.SELECTION_MODE_NONE);
  </code></pre>
  
  <p>How to implement that? where i am going wrong?</p>
  
  <p><strong>UPDATE</strong>:
  After taking the login of Umar and Manny i updated my code like this:</p>
  
  <pre><code>materialCalendarView.setSelectionMode(MaterialCalendarView.SELECTION_MODE_NONE);
  
      Calendar calendar = Calendar.getInstance();
      calendar.set(2017, 12, 14);
  
      Calendar calendar2 = Calendar.getInstance();
      calendar.set(2017, 12, 15);
  
      Calendar calendar3 = Calendar.getInstance();
      calendar.set(2017, 12, 16);
  
      Calendar calendar4 = Calendar.getInstance();
      calendar.set(2017, 12, 17);
  
  
      materialCalendarView.addDecorator(new CurrentDayDecatator(getActivity()));
      materialCalendarView.setDateSelected(calendar, true);
      materialCalendarView.setDateSelected(calendar2, true);
      materialCalendarView.setDateSelected(calendar3, true);
      materialCalendarView.setDateSelected(calendar4, true);
  </code></pre>
  
  <p>So, now i get only the last date selected which is calendar4. But still i am unable to select multiple dates. and by default materialCalendarView selects today's date.</p>
