Error when trying to access the property __dict__ of an object that hasn't one. #149
Description
If a script has an object that hasn't the property dict, for example, a dtype, an error happens in the function "def full_member_lookup(self, collection, vcontainer, vindex, value, depa)" of the file "now/collection/prov_execution/collector.py". This occurs in the line "if vindex in vcontainer.dict:" when the code tries to access a property that doesn't exist.
