#11710: is_simple - empty geometry logic

------------------------------+---------------------------
 The logic around dealing with empty datasets and is_simple seems a little
 confusing:

 An empty line - seg fault (see
 https://svn.boost.org/trac/boost/ticket/11709)
 An empty multi line - returns false
 An empty polygon - returns true
 An empty multi polygon - returns false

 Should a multi polygon or linestring that is empty be considered simple. I
 would think it would as it would not have any anomalous geometric points,
 such as self intersection or self tangency.
