Hosting the app on a server

[see24]

There is currently a demo version here. This is only to see what the app can do using a toy data set.

Options for hosting could include shinyapps.io which has various price tiers I think we would need a paid tier to allow the size of files we need. Some other options are described here

Would need to change the way files are loaded. Currently we use shinyFiles to access local files on the users computer but this would not work if the app is running on a server. Would need to change to a fileInput shiny element which uploads the file to the server for use in the app. See here

Will also need to deal with the fact that shapefiles need multiple files and that gets messed up with the shiny fileInput. This idea could potentially work: https://gist.github.com/RCura/9587685

It is not clear to me how well the limits on files size etc could affect the app. I need to learn about how to predict the amount of resources that the app will need.

Instead of re-jigging all the file inputs we could have a spot where users upload all the files in a zipped folder and then they can pick each file individually after that. This is not an ideal solution but would allow using real data faster
