Extraction of plumtree_metadata.

[cmeiklejohn]

plumtree_metadata should be it's own package, given it's an implementation of a KVS on top of the protocol -- this is not required, and may not be desired by all users of the library. (Additionally, by extracting this library, the eleveldb dependency is no longer required as part of the core protocol.)

Yea, I was just looking at plumtree again because I was thinking of replacing machi's naive 'send to everyone' with it but am not willing to bring eleveldb back in as a dependency :).

I'll probably look at doing this myself but wanted to check in case any work by others had already been done.

The Lasp fork does not have the eleveldb dependency nor the metadata store.

Oh, great!
