### traverse\_changesets { after =\> SEQUENCE\_NO, UNTIL =\> SEQUENCE\_NO, callback =\> sub { } }

Walks through all changesets from `$after` to `$until`, calling `$callback` on each.

If no `$until` is specified, the latest changeset is assumed.

Returns an ordered set of changeset objects for all changesets containing changes to this object.

If "limit" is specified, only returns that many changesets (starting from record creation).

Note that changesets may include changes to other records

Returns a reference to a list of record objects for all records of type `$type`.

Order is not guaranteed.
