Initialize segments_Segment_Type.tp_base and segments_SegmentList_Type.tp_base at run time
This is required to build 'glue' for Windows, which is required (now) to build PyCBC for use on Einstein@Home.
In Python on Windows, &PyTuple_Type and &PyList_Type aren't known at compile time, so one gets an 'initializer is not constant' error when compiling the 'segments' module there. The solution is to Initialize segments_Segment_Type.tp_base
and segments_SegmentList_Type.tp_base
at run time.
