/**
* A mutation describes a self-contained change to a document. Mutations can
* create, replace, delete, and update subsets of documents.
*
* Mutations not only act on the value of the document but also its version.
*
* For local mutations (mutations that haven't been committed yet), we preserve
* the existing version for Set and Patch mutations. For Delete mutations, we
* reset the version to 0.
*
* Here's the expected transition table.
*
* MUTATION APPLIED TO RESULTS IN
*
* SetMutation Document(v3) Document(v3)
* SetMutation NoDocument(v3) Document(v0)
* SetMutation InvalidDocument(v0) Document(v0)
* PatchMutation Document(v3) Document(v3)
* PatchMutation NoDocument(v3) NoDocument(v3)
* PatchMutation InvalidDocument(v0) UnknownDocument(v3)
* DeleteMutation Document(v3) NoDocument(v0)
* DeleteMutation NoDocument(v3) NoDocument(v0)
* DeleteMutation InvalidDocument(v0) NoDocument(v0)
*
* For acknowledged mutations, we use the updateTime of the WriteResponse as
* the resulting version for Set and Patch mutations. As deletes have no
* explicit update time, we use the commitTime of the WriteResponse for
* Delete mutations.
*
* If a mutation is acknowledged by the backend but fails the precondition check
* locally, we transition to an `UnknownDocument` and rely on Watch to send us
* the updated version.
*
* Field transforms are used only with Patch and Set Mutations. We use the
* `updateTransforms` message to store transforms, rather than the `transforms`s
* messages.
*
* ## Subclassing Notes
*
* Every type of mutation needs to implement its own applyToRemoteDocument() and
* applyToLocalView() to implement the actual behavior of applying the mutation
* to some source document (see `setMutationApplyToRemoteDocument()` for an
* example).
