Basic web GUI for Prospector

[copernico]

This could be a simple page where one can enter (some of) the basic input parameters of the client.cli.prospector() function and submit the corresponding "search" job to the backend. The immediate response from the backend contains a job id that allows the results to be polled (e.g., every second or so) and eventually the results can be displayed on the page, with clickable links and collapsible panes showing the relevant details of each candidate and the reason why it was ranked the way it was.

Not urgent, but definitely valuable both for practical use as well as for demonstration purposes.

I suppose this is something relatively easy to implement for anyone with some basic knowledge of React or similar frameworks.
