Add some ideas for charm constituents.

Not particularly useful in its own right, but contains some possibly
useful ideas related to the generalisation of db-compositions.

;; This aims to bolt on Charm compliance 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.
