Added Single Parent Flag #110

Closed nathanial closed 6 years ago

nathanial commented 6 years ago

This PR attempts to address Issue #103. I've added a singleParent flag to the Freezer constructor that makes the addParent function throw an exception if a node is about to get multiple parents. The default for the flag is false, so no existing code should be effected.
