last update broke the metadata package (until new pytypes release)

I'm currently getting

  File "/home/davjoh/Envs/spider/lib/python3.6/site-packages/d3m_metadata/types.py", line 30, in <module>
    type_util.resolve_fw_decl(Data)
AttributeError: module 'pytypes.type_util' has no attribute 'resolve_fw_decl'

when trying to run anything using this package. By the sounds of https://github.com/Stewori/pytypes/issues/22 it could be a little while before the new pytypes is released, so I'd suggest rolling back the recursive typing support until then.
