* Start splitting apart reconciler, with tests
* Reify children in reify
* Baseline hydrate implementation
* Remove debug print
* Scaffold out diff implementation, just supporting name changes
* invariant -> error in decodeValue
* Flesh out diff and add getProperty
* Clear out top-level reconciler interface, start updating code that touches it
* Address review feedback
* Add (experimental) Selene configuration
* Add emptiness checks to PatchSet, remove unimplement invert method
* Improve descendant destruction behavior in InstanceMap
* Track instanceId on all reify errors
* Base implementation of applyPatch, returning partial patches on failure
* Change reify to accept InstanceMap and insert instances into it
* Start testing applyPatch for removals
* Add test for applyPatch adding instances successfully and not
* Add , which is just error with formatting
* Correctly use new diff and applyPatch APIs
* Improve applyPatch logging and fix field name typo
* Better debug output when reify fails
* Print out unapplied patch in debug mode
* Don't write properties if their values are not different.
This was exposed trying to sync the Rojo plugin, which
has a gigantic ModuleScript in it with the reflection
database. This workaround was present in some form in
many versions of Rojo, and I guess we still need it.
This time, I actually documented why it's here so that
I don't forget for the umpteenth time...
* Add placeholder test that needs to happen still
* Introduce easier plugin testing, write applyPatch properties test
* Delete legacy get/setCanonicalProperty files
* Fix trying to remove numbers instead of instances
* Change applyPatch to return partial patches instead of binary success
* Work towards being able to decode and apply refs
* Add helpers for PatchSet assertions
* Apply refs in reify, test all cases
* Improve diagnostics when patches fail to apply
* Stop logging when destroying untracked instances, it's ok
* Remove read before setting property in applyPatch
* Fix diff thinking all properties are changed
* Changes project-related structures to use `BTreeMap` instead of `HashMap` for children to aid determiniusm
* Changes imfs-related structures to have total ordering and use `BTreeSet` instead of `HashSet`
* Upgrades dependencies to `bx_dom_weak`1.2.0 and rbx_xml 0.5.0 to aid in more determinism stuff
* Re-exposes the `RbxSession`'s root project via `root_project()`
* Implements `Default` for a couple things
* Tweaks visualization code to support visualizing trees not attached to an `RbxSession`
* Adds an ID-invariant comparison method for `rbx_tree` relying on previous determinism changes
* Adds a (disabled) test to start finding issues in the reconciler with regards to communicativity of snapshot application
* Adds a snapshot testing system that operates on `RbxTree` and associated metadata, which are committed in this change
