title: How do I change the default height of a BottomSheetDialog?
body: <p>I've been using the new BottomSheetDialog added in <a href="http://android-developers.blogspot.com/2016/02/android-support-library-232.html">Support Library 23.2</a>, but I want to change the default height of the dialog. I know it probably has to do with the <code>behavior_peekHeight</code> attribute which controls the initial height, but how do I set that in the <code>BottomSheetDialog</code> when I don't have direct access to the <code>BottomSheetBehavior</code>?</p>
