Fix performDecoration for single node graphs #143

Closed Boarders closed 5 years ago

Boarders commented 5 years ago

Currently performDecoration from Analysis.Scoring does not work correctly for single node graph. In particular, it returns an empty graph. Whilst this is not the standard use case it is conceivable this is situation arises and we should handle it correctly.
