title: how to disable Pull-Up-Refresh in PullToRefreshScrollView?
body: <p>I use PullToRefreshScrollView in <a href="https://github.com/chrisbanes/Android-PullToRefresh" rel="nofollow">https://github.com/chrisbanes/Android-PullToRefresh</a>. </p>
  
  <p>It includes PullDownToRefresh and PullUpToRefresh,but I don't need the PullUpToRefresh since I get a Bottom MenuDrawer; </p>
  
  <p>I guess there might be a parameter to store the refresh action in the source  code.Please help me to solve this problem</p>
