versionId: string
noteId: string
userId: string
content: string // same as note content (compressed)
title: string

restored: boolean

Store a list of the note revisions against the note model. Each version will have a primary UUID versionId and a secondary index of noteId and a global secondary index of userId. The note model will also store a list of versions with each version containing the following subset of the version model:

versionId: string
noteId: string
title: string
dateCreated: number
restored: boolean
