handle empty contraction list in PathInfo #229

Closed jcmgray closed 1 month ago

jcmgray commented 2 months ago

Description

This simply handles the case when PathInfo is constructed with an empty path (e.g. for the no-op contraction eq="->") with some defaults rather than raising ZeroDivisionError. See https://github.com/jcmgray/quimb/issues/231.
