Store EIEIO objects using EmacSQL
=================================
Store uniform [EIEIO] objects in an [EmacSQL] database. [SQLite] is
used as backend. This library imposes some restrictions on what kind
of objects can be stored; it isn't intended to store arbitrary
objects. All objects have to share a common superclass and subclasses
cannot add any additional instance slots.
