Feature request: Output trade DMs for an entire sector or subsector

[adajd]

For player reference, it would be helpful to be able to output the trade DMs (i.e. the information in the “Trade Preview” section) for an entire sector or subsector at once.

It would also be helpful to include the average purchase and sale price for each trade good with a non-zero DM on each world (i.e. the price generated by an average dice roll).

This would essentially generate a “commercial atlas”, as detailed in this post on Freelance Traveller: http://www.freelancetraveller.com/features/rules/commatlas.html
