I also had to use get/put_data_info and get/set_frame_time.  Is there
any reason that the frame_time is not part of the data info structure?
The other problem with this approach is that flux-correction does not
work.

Regarding combine_datasets and groups, have you considered putting
each dataset into its own group and then change the semantics of the
plot, notice, ignore, etc functions to take a group id instead of a
data set id?  By putting each data set into its own group, the
functions would work as before.  For example, suppose that group-ids
are numbered from a number such as 0x4000 (16384) and that one has 4
datasets loaded with dataset ids 1,2,3, and 4.  In addition, suppose
that 2 and 3 have been grouped such that the group id is 16384.  Then,
plot_model_counts(3) would plot the model folded through the responses
for dataset 3.  But, plot_model_counts(16384) would plot the model
folded through the responses for 2 and 3.  Also, list_data could show
the group 16384 with the counts column given by the sum of counts of
the group members.

(Although this seems like a useful abstraction, it is probably not
 worth the effort since I doubt that few people use groups.
 Nevertheless, I felt I had to ask since we are nearing that time of
 the year when I have to start thinking about what to give someone that
 has everything he needs.  Isis is in more or less the same boat.)

Thanks,
