parse_mmCIF_file() tries to import structaccess within C++ and fails

[Tom Goddard]

Using pdbio.parse_mmCIF_file() from Hydra gives the error "No module structaccess". Apparently the C++ for parse_mmCIF_file() attempts to do the equivalent of "import structaccess". But structaccess is not found because it is installed within the hydra package, as is the pdbio module, so "from hydra import structaccess" would be needed.

I think the simple solution to this is to merge structaccess into the pdbio module. It is awkward if parse_mmCIF_file(), a function in pdbio needs to return a value of a type that pdbio doesn't know about.

Moot now that PDBio will no longer be creating blobs.
