I'd like to plot vectors in kst, basically some values vs time. And I 
would like to load strings from the header, the field names and units, 
to display these in the legend.

The file structure is simple, it consists of blocks of equal size (64 
bytes), except for the header, where field names and some more data is 
stored.

Most of the blocks contain the vectors I want to plot (but no time 
information). To be able to plot vs time, I assume a fixed time interval 
between consecutive vector blocks. The other blocks contain a time stamp 
that is used for synchronisation (these have an event code attached).

For the more distant future, if I find time for it, I would like to 
display a list of events in kst ("Date/Time - Event name"), derived from 
the file, and use that to navigate through the plots. That would help me 
a lot to quickly get to the interesting spots.
