issue #10 initial implementation
- references to .dist.cfg.tables in the internal functions replaced with references to .dist.status - internal state now depends only on .dist.status
- new .dist.addTable[] function - ad-hoc table adding
- on init: tables which exist on disk in cfg.jrnDir directory, but are not configured in the dataflow.cfg are now added initialized basing on disk state and added to .dist.status
- TODO: input validation
- TODO: cfg vs disk state validation
