Need to get the Change objects have a particular document/part/etc. as part of the change.
As part of validating a Change Notice before approval, we want to make sure the Resulting objects have not already been part of another change. We can check states on the docs for most cases, but sometimes we need to take the resulting documents and look at any other CNs that are also trying to validate. I already have the code that takes a CN and returns the list of Resulting documents, parts, etc. What code takes a document and returns the list of CNs containing it?
