Description (modules)

I would like the "description.md" to be built automatically with sky culture makers then arranging the input fields in always the same way. For the standard structure, I think:

• Licence and Author name have to be put directly below the headline for immediate recognition (like in research papers); this would also give the description a more "professional" appearance
• Then "description of the culture" (where it is on Earth, what's special about it etc.)
• then, "description of the sky of this culture", e.g. list of constellations, notes on features like zodiac division etc. ...
• then, of course the formal things (as it is now): reference, classification, region
