This restructures the doc as a tutorial leading newcomers to becoming experimented users.
It adds pages on:
- how to get started with Cartographer on a new .bag
- how Cartographer works and can be tuned step-by-step
- how to use "extra" features of Cartographer
- how to contribute to Cartographer
It also provides some cosmethic changes with: new titles, non-indented code blocks, various illustrations, reworked paragraphs for clarity...
Other changes:
- Moved the 'Verification' paragraph in the tuning guide up,
as it fits better after the particular issue discussed before 'Special Cases'.
- Fixed 'WARNING: Title underline too short.' messages.
