#include <spline/xmlio.hpp>Read and write B-Spline curves from XML files. The format of the XML object is as follows:
<spline_curve>
<spline_order>3</spline_order>
<!-- optional,
if no knots are provided, equidistant knots starting at 0
are used (as below) -->
<knot>0.0</knot>
<knot>1.0</knot>
<knot>2.0</knot>
<knot>3.0</knot>
<knot>4.0</knot>
<knot>5.0</knot>
<knot>6.0</knot>
<!-- use the right string represention of DATA_t
within the coefficient-tags -->
<coefficient>(0, 0)</coefficient>
<coefficient>(1, 0)</coefficient>
<coefficient>(1, 1)</coefficient>
<coefficient>(0, 1)</coefficient>
</spline_curve>
