[metatreedb] modify test/store to run new metadata
[metatreedb] remove meta from indexer
[metatreedb] add meta from epochmeta project

this is a generic driver that takes controllers
and operations to do specific things for each usecase
[metatreedb] packagejson now includes epochmeta in devDeps

this contains the specifics for running metadata
on epochtalk (for example/test use only)c
[metatreedb] epochmeta included in meta opts
[metatreedb] include metadata in index

uses the opts.meta argument
actually test metadata in test/store
temporary fix for meta tests
update store to use setTimeout

this is kinda 'ghetto' tho
