/**
 * An example of adding these transitions to a Fragment.  This simple
 * version just applies opposite transitions to any Fragment whether it is
 * entering or exiting view.  You can also inspect the transit mode parameter
 * (i.e. TRANSIT_FRAGMENT_OPEN, TRANSIT_FRAGMENT_CLOSE) in combination to do
 * different animations for, say, adding a fragment versus popping the back stack.
 * 
 * Transactions without an explicit transit mode set, in this example, will not
 * animate.  Allowing the initial fragment add, for example, to simply appear.
