The registry stores data about your messages: relations, marks and such.
Its mostly a function message-id -> data in the mathematical sense, so
it's stored using a big hash table.  More or less.

It's implemented using the `eieio-persistent' class.

It allows to attach additional information to messages, like user
defined marks or anything else.  Allows to jump to parent messages that
are not part of the current group.  Such things.  Gnus then knows about
all your messages and where they are.
