/**
* Builds the structure of the right-side panel containing configuration and assorted tools.
* It includes the regular tabs, to configure the Page (including several sub-tabs), and Field;
* and allows other tools, such as Activity Feed, to be rendered temporarily in its place.
*
* A single RightPanel object is created in AppUI for a document page, and attached to PagePanels.
* GristDoc registers callbacks with it to create various standard tabs. These are created as
* needed, and destroyed when hidden.
*
* In addition, tools such as "Activity Feed" may use openTool() to replace the panel header and
* content. The user may dismiss this panel.
*
* All methods above return an object which may be disposed to close and dispose that specific
* tab from the outside (e.g. when GristDoc is disposed).
