some very sketchy Charm constituent code

+;;;=====================================================================
+
+;;; This aims to bolt on Charm compliance (including database
+;;; versioning) to AMuSE constituents as they are currently implmented
+;;; (i.e. compositions primarily). However, in order to avoid breaking
+;;; existing code, this is not the most tidy of solutions.
+
+;;;=====================================================================
+;;; Charm property lists
+;;;
+;;; Many things I don't like about this. Using the class hiererchly
+;;; for these kinds of properties might be nicer.
