/**
 * 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).
