Those were there when this application didn't use fragmented
tables.
Now, all the buckets are fragmented by default and we provide
the grow/1 and shrink/1 functions to expand the tables along
with the fragment properties.
This is a small abstraction layer on top of mnesia. It simplifies
table management and addition of replicas and nodes.
Some things to add in the near future:
* Removing nodes from a mnesia cluster is not supported.
* Observability and event handling is missing.
While it's possible to perform the aformentioned functions with
the mnesia own APIs, adding some simplifications for day to day
management may be a good idea.
However, the library is already used in another project and it's
good enough for an initial use. It will be extended if and when
required.
