Sync design

[anthonygarvan]

• data stored as rows with entries of {id: 'zfregln', text: 'This is bold', createdOn: 'isostring', 'lastModified': 'isostring'}
• rows are chunked by 200 - 300 lines, sent to json-stringify-deterministic, hashed
• query google drive to get file metadata
• if the app has most current metadata (no contention), save new file metadata with list of ids
• list files in file contents folder
• add additional file data
• remove any files that no longer have references

to load file:

• get file metadata
• check cache to see if md5 hash is in localstorage, use it if so
• if not query to get the file data block
• assemble all blocks into file object
• create index
