STATION sub-command:

This command can be used to add a new station:

> trade.py station --add "i bootis/nowhere port"
> trade.py station -a "i bootis/nowhere port" --ls 123 --pad m

Or it can be used to delete a station:

> trade.py station --remove "i bootis/nowhere port"
> trade.py station -rm "i bootis/nowhere port"

Or it can be used to update the ls-from-star, pad-size, or blackmarket

> trade.py station --update "i bootis/nowhere port" --pad=L --ls-from-star=123 --black-market=N
> trade.py station -u "i bootis/nowhere port" --pad L --ls 123 --bm=N

Crop Harvesters* @ 2,568cr (Avg Buy 1,997cr)

This shows that 'Tea' is a star buy at this station: it is being
sold by the station for 1217cr but the average selling price is
1570credits.

A star trade (indicated by '*') is at least 10% better than the
average trading price for that commodity.
