v0.91

Features

• Inclusion: Implemented a mechanism to control the inclusion of properties of specific object types.
• Inclusion: Implemented a mechanism to register custom inclusion resolvers to support inclusion rules far beyond the built-in ones.
• Introspection: Implemented a mechanism to register a custom instance factory, which is used by DiffNode#canonicalSet in order to create instances of missing objects

Improvements

• Inclusion: Performance improvements (Thanks @Deipher)
• Inclusion: InclusionService has been split into several InclusionResolvers
• DiffNode: canonicalSet now automatically creates missing objects along the path to the root object

Bugfixes

• Circular Reference Detection: Fixed 'Detected inconsistency in enter/leave sequence. Must always be LIFO.' bug that could occur due to inconsistent cleanup of the instance memory when a circular reference has been detected.
