// Abstract base class for TabContainer. Must define _makeController() to instantiate
// and return the widget that displays the tab labels
// description:
// A TabContainer is a container that has multiple panes, but shows only
// one pane at a time. There are a set of tabs corresponding to each pane,
// where each tab has the name (aka title) of the pane, and optionally a close button.
// tabPosition: String
// Defines where tabs go relative to tab content.
// "top", "bottom", "left-h", "right-h"
tabPosition: "top",
baseClass: "dijitTabContainer",
// tabStrip: [const] Boolean
// Defines whether the tablist gets an extra class for layouting, putting a border/shading
// around the set of tabs. Not supported by claro theme.
tabStrip: false,
// nested: [const] Boolean
// If true, use styling for a TabContainer nested inside another TabContainer.
// For tundra etc., makes tabs look like links, and hides the outer
// border since the outer TabContainer already has a border.
