Related maps feature #146
Description
Contextualise allows you to create as many (independent) topic maps as you want. Nevertheless, I have seen over time that I am using various informal mechanisms (e.g., a link in a topic note or in the topic text) to link the current map to other related maps. This could imply that I either should be using just one "super" map :) or that Contextualise needs a formal way to manage related (top-level) topic maps. I obviously opt for the second alternative :)
