4f1d064521ce3b781f7a6a03c6ec56034232c6b4	BUG: adresses #738 I have added a simple behavior for complex numbers in _maybe_promote. When reindex operations return nan, complex numbers are not cast to objects. A test has been added to test_dataarray.py which validates the behavior.	2016-02-02T17:57:36Z	2016-02-04T21:15:31Z	c0018c19c8398285fefe5ce007d76e929a3a4a66	c0018c19c8398285fefe5ce007d76e929a3a4a66	13221727	11950875	11950875
