after running some tests with larger files, I have added the following paragraph
to the HTML page:
"using the Filed() macro comes at a run-time cost, alas. for data sets of
hundreds, or low thousands, of records, the time taken is unnoticeable, though
if there are hundreds of thousands or more, it may (in an animation, perhaps)
become enough of an issue to consider sticking with the #read and #write
with 100k sphere centre and radius records for instance, POV-Ray needs around
one second for the writing and the same for the read back. Filed() comes in at
around eight seconds write and ten seconds read.
