Range Editor

This is mentioned in many places as a future app but until now doesn't have its own issue.

The idea mentioned in #43 (comment) - the grid, plus a tabular UI for the "manifests" - suggests a possible UI for a range editor.

See #41 for a user narrative involving Range editing.

This is the old description from #41, which describes creating hierarchical ranges:

Once I'm happy the canvases are in the right order, I switch into the Range Editor mode, which replaces the normal view with tool that is just for creating ranges. On one side there's a tree structure (although it starts empty) and on the other is the field of canvas thumbnails again. But now I can select multiple Canvases and create a Range, then with that Range selected in the Tree, create a child Range, and so on. This way I can mark the chapters out quickly. Sometimes I can do this visually just from the thumbnails but sometimes I need to look at the page in more detail to check it's the chapter end/beginning. I can click on a thumbnail to make it fill the screen for a moment, and then dismiss it.

Then in #43 (comment), an interface is suggested for splitting a manifest into smaller manifests by making selections, with a table-style UI.

This can be the same Range editor - the user is choosing not to create child ranges of the ranges; the ranges don't have to be contiguous and may overlap (the same canvas could appear in multiple Ranges). The ranges are assigned a custom behavior that can be recognised by an external process that creates new Manifests from this "marked up" manifest. That suggests that:

• you could open the range editor tool in a mode that understands it's for manifest-marking; it prevents child ranges and automatically assigns this behavior.

If you then want to create hierarchical (or flat) table-of-contents style ranges within the created manifests, you'd have to go and open those manifests and edit them; to keep things simple you wouldn't mark out the ranges for splitting and create their internal navigation Ranges at the same time.

Discovery - work out if we need a hierarchical range editor in addition to the version described in #43 and in the above comment. Possibly not for any first phase.
