prototype modelling visualisation

[jameshadfield]

There are a number of points which have been raised recently about how the modeling data should be presented. They include:

• The display of time as a variable (e.g. heat-map style tables)
• The display of other "group-by" or faceting variables
• The UI to choose between different models, different outcomes etc
• Ability to select different pathogens, including to explore co-infection
