Regarding the last point: maybe these structures should not be wrapped
into an octave_value, since the user must configure them (so either a
couple of function for configuration would be needed, or a
representation of these structures in regular Octave cells/structures
defined). Maybe these structures should _only_ be represented as
Octave cells/structures and the corresponding comedi structures be
generated on the fly by comedi_cmd() et al.
