document sharding

[lun-4]

at the moment each document can only have 2048 characters, we should be able to expand over that limit.

we can do this by converting the document into a shard index once it goes over 2k chars, that index message contains all the message ids of the other shards, reassemble and kaboom you get a document

the index message itself might get over 2k chars too, so the database should handle multi level marketing multi level indexing so that we can infinitely scale to a gigabyte of data!!!!!!
