Weighted points

[dabreegster]

Let the user specify a weight per origin or destination point. When randomly sampling points inside a zone, use this weight.

• Make an example demonstrating this feature clearly
• Document it (and more generally, overhaul the docs on config and input formats)

This is great to see! Thanks for opening it.

Can have a look at docs, good timing for use cases.

One thing I can do: add minimal input for tests. Will track that here, when I get a chance.

Thanks! Ultimately I'd like the docs to have some discussion of how to make good input data. For using OSM buildings, for instance, the user needs to be aware of the uneven coverage. For weighting, I'm not sure in practice how to pick weights, other than vague ideas like "more square footage for a shop means more important" and "flats with more height are more important"

Well that can be a problem for the user to figure out.. Will aim to get a minimal example input dataset today. One observation: lots of the examples in the examples folder are big, could be good to have small ones like 10 zones to 1 destination I'm thinking.

Taking a look at this now...

Just discussing this with @wangzhao0217, and looking to use this functionality in NPT work.

I'll try and catch up on PRs / docs for this soon then. Keep me posted how you actually decide the weights!
