This follows from the discussion in the thread at
http://thread.gmane.org/gmane.science.nmr.relax.scm/24009/focus=7228.

the space mapping (the map.setup user function), creating the map, storing all data in the current
data pipe, and having user functions for outputting the data for OpenDX, matplotlib and plain text.
