/**
 * @return a new cursor based on the given cursor with all duplicate destinations removed.
 *
 * It's only intended to use for the alternate list, so...
 * - This method ignores all other fields and dedupe solely on the destination.  Normally,
 * if a cursor contains multiple contacts and they have the same destination, we'd still want
 * to show both.//from   w  ww . j a v  a  2 s  .  c  o m
 * - This method creates a MatrixCursor, so all data will be kept in memory.  We wouldn't want
 * to do this if the original cursor is large, but it's okay here because the alternate list
 * won't be that big.
