Test the proposed title TreeView API:

	export interface TreeView<T> {
		/**
		 * The name of the tree view. It is set from the extension package.json and can be changed later.
		 */
		title?: string;
	}

The tree view sample extension is a good place to start: https://github.com/microsoft/vscode-extension-samples/blob/master/tree-view-sample/src/testView.ts#L6

• Verify that the inline documentation makes sense.
• Verify that the title of the tree view is correctly sourced from the package.json first
• Verify that you can get the title as set in the package.json even if you never set it.
• Test that you can always get the title.
• Test that you can change the title
