Colour nodes in network diagram using categories for "relationship with case"

[bernardsilenou]

Feature Description

The transmission chain nodes can be coloured by case classification only.

Problem Description

• In a transmission chain of only confirmed cases, it does not make sense to visualize nodes by case classification. It is good to visualize the different types of relationship that resulted to infections

  Proposed Change

• add a check box called "colour nodes by relationship with source case"
• If source case is case0, in the transmission chain, use red. If node0 is an event, use blue.
• for cases resulting from event, relationship with case == social
• for cases resulting from returning traveler contact without a source case, relationship with case == travel

@bernardsilenou In the long run we might also want to consider display options for color blind people.
