   Currently the xml loader controls what is done with the data, but with
   the curves, you might want to control where the stp_curve_t ends up
   (i.e. assign it yourself).

   The loading is done in two stages:
   1. XML file -> in core XML tree representation
   2. XML tree -> stp data structures

   If the user were to do the first stage themselves, then they can
   control what is done with the data, i.e.:

   xmlNode *xmlcurve = ...; /* XML curve node */
   stp_curve_t curve = stp_xml_process_curve(xmlcurve);

   When wanting to output (or embed) the curve in an XML file, then the
   reverse could be done:

   stp_curve_t curve = ...;
   xmlNode *xmlcurve = stp_xml_curve_create(curve);

   Then this can now be added to a larger tree, and/or saved to a file.

I think I'd like to retain something like the stp_curve_read()
interface, so that merely saving/loading a curve doesn't require
knowledge of XML, if that's possible.
