/*Marcus G Daniels, swarm-support 03/18/2001 

In today's snapshot there is low-level support for extending simple
vector HDF5 datasets.  This feature is useful if you have several data
streams coming out of a simulation and you want to record them and
load them later into R.  Note I haven't merged it with the analysis module --
maybe someone would find that useful and do the work...

Here's an example of use of the `extensible double vector' methods in
the HDF5 interface.  (Note this isn't object serialization.)*/
