• Originally I had a concept of a readonly node tree for grammars with nodes owning other nodes thinking it would be necessary when tokenizing. It isn't, so they're more trouble than they're worth.
• "ownership" in Grammar\Reference objects is handled by an ownerGrammarScopeName property which is then used to get the grammar from the GrammarRegistry.
• Added preliminary transformation of out-of-range codepoints in matches
• Fixed adoption of Grammar\Pattern objects.
• Fixed retrieval of Grammar\RepositoryReferences.
