Motivation

There may be situations where you may want to remove signers.

Design

To do this you would need to perform a resharing protocol and leave out the relevant participant.

This is done by basically redoing the trusted dealer generation with a "zero" secret, and adding the new shares to the old ones, while keeping only the participants that are wanted

I changed this issue to "remove signers or refresh shares" since the technique is the same.
