Changes "Structure & Cost" report to "Overview", as the goal for this
report is improved.
The point is to have on a single report all components and sub-assemblies
that make it up, in parallel with the route and lead times associated to
each. This way it becomes easier to identify issues, such as:
- Missing routes.
- Longer lead times on a specific sub-assembly.
- Unavailable component in the foreseable future.
- ...
Also did the conversion to OWL, changing drastically the structure of
the report.
