Vignette: assessment of uncertainty

[famuvie]

Produce a worked-out case study on uncertainty quantification.

This needs to be done programmatically (i.e. without the interface). Make explicit the inputs that have some uncertainty (basically, the weights) and make a function that produces the risk map given an input.

Make some sensible assumptions about the uncertainty on the weights and produce maps from a sample of possible weights.

Finally, compute some maps summarising the weighted average risk map and quartile maps, sd maps, etc.

Eventually, we could enhance the interface to allow introducing uncertainty assessments for the input pair-wise comparison matrix in order to produce the uncertainty map automatically.
