@sbillinge please check, thanks

Normalize paths before assert in test_serialization/test_load_multiple to prevent possible Windows short/long name mismatch.

Merged. Do we have to push out a new patch-release for cmi tests to pass?

[Tieqiong]

@sbillinge Not really necessary. I already released one in my personal fork and now cmi tests are using that release. Also made an issue diffpy/diffpy.cmi#35 on this.
