-### get(id, cb)
-
-Will get a message with `id` from the database. If the message is not
-found an err will be returned.
-
-### getSync(id, cb)
-
-Same as `get` except this method will wait for the indexes to be in
-sync with the main log.
-
-### validateAndAdd(msg, cb)
-
-Validate a raw message (without id and timestamp), meaning if its the
-first message from the feed, validate it without the previous pointer
-otherwise it has to be the next message for the feed. Callback is the
-stored message (id, timestamp, value = original message) or err.
-
-### validateAndAddOOO(msg, cb)
-
-Works the same way as validateAndAdd, expect that it will always do
-validate without the previous pointer, meaning it can be used to
-insert out of order messages from the feed.
-
-### add(msg, cb)
-
-Add a raw message (without id and timestamp) to the database. Callback
-is the stored message (id, timestamp, value = original message) or
-err.
-
-### get(key, cb)
-
-Get a message based on the key. Callback is the stored message (id,
-timestamp, value = original message) or err.
-
-### del(key, cb)
-
-Remove a message from the database. Please note that this can create
-problems with replication, in that a remote peer that does not have
-this message will not be able to get this messages and any message
-that comes afterwards.
-
-### deleteFeed(feedId, cb)
-
-Delete all messages for a particular feed and removes any state
-associated with the feed.
-
-### getStatus()
-
-Gets the current db status, same functionality as

-
-Returns a [jitdb] instance of the database useful for queries.

-### getLatest(feedId, cb)

-Returns the latest state ({ id (msg key), sequence, timestamp }) for a feedId.
