- Support interface properties as with JSBSim for easy reuse
and parametrization of autopilot components.
- Add property-root property to allow changing property root
for all relative paths. This allows easy use of multiple
instances of the same autopilot component at the same time
by specifiying different property root nodes.
Split the former single-file-implementation in xmlauto.?xx into multiple
files and use some OO techniques. Started with documentation to be used
with doxygen.
