Summary
This PR fixes an issue where if someone put an object inside a
DataContextand then later split the context, the context splitter would only perform a shallow copy, meaning that modifications to the object would be shared across all contexts for that step.The issue is resolved in this PR by performing a deep copy. A regression test has also been added to ensure that this bug does not appear again.
Closes #6
