Implement contributed views those can be shown in Explorer as trees.

• Contribution point to describe a view
• API to register a tree data provider for the view
• Multi views explorer

Actions can be contributed to the following locations by giving proper when clause

• View titlebar: view/title
• On item:view/item/context

Example:

"contributes": {
    "menus": {
         "view/title": [
	    {
		"command": "extension.commandId",
		"when": "view == viewId",
		"group": "navigation"
	    }
         ],
         "view/item/context": [
	     {
		"command": "extension.commandId",
		"when": "view == viewId && viewItem == contextValue",
	      }
          ]
   }
}
