+/**
+ * Class: mxDefaultPopupMenu
+ *
+ * Creates popupmenus for mouse events. This object holds an XML node
+ * which is a description of the popup menu to be created. In
+ * <createMenu>, the configuration is applied to the context and
+ * the resulting menu items are added to the menu dynamically. See
+ * <createMenu> for a description of the configuration format.
+ * 
+ * This class does not create the DOM nodes required for the popup menu, it
+ * only parses an XML description to invoke the respective methods on an
+ * <mxPopupMenu> each time the menu is displayed.
+ *
+ * Codec:
+ * 
+ * This class uses the <mxDefaultPopupMenuCodec> to read configuration
+ * data into an existing instance, however, the actual parsing is done
+ * by this class during program execution, so the format is described
+ * below.
+ * 
+ * Constructor: mxDefaultPopupMenu
+ *
+ * Constructs a new popupmenu-factory based on given configuration.
+ *
+ * Paramaters:
+ *
+ * config - XML node that contains the configuration data.

+/**
+ * Function: createMenu
+ *
+ * This function is called from <mxEditor> to add items to the
+ * given menu based on <config>. The config is a sequence of
+ * the following nodes and attributes.
+ *
+ * Child Nodes: 
+ *
+ * add - Adds a new menu item. See below for attributes.
+ * separator - Adds a separator. No attributes.
+ * condition - Adds a custom condition. Name attribute.
+ * 
+ * The add-node may have a child node that defines a function to be invoked
+ * before the action is executed (or instead of an action to be executed).
+ *
+ * Attributes:
+ *
+ * as - Resource key for the label (needs entry in property file).
+ * action - Name of the action to execute in enclosing editor.
+ * icon - Optional icon (relative/absolute URL).
+ * iconCls - Optional CSS class for the icon.
+ * if - Optional name of condition that must be true (see below).
+ * enabled-if - Optional name of condition that specifies if the menu item
+ * should be enabled.
+ * name - Name of custom condition. Only for condition nodes.
+ *
+ * Conditions:
+ *
+ * nocell - No cell under the mouse.
+ * ncells - More than one cell selected.
+ * notRoot - Drilling position is other than home.
+ * cell - Cell under the mouse.
+ * notEmpty - Exactly one cell with children under mouse.
+ * expandable - Exactly one expandable cell under mouse.
+ * collapsable - Exactly one collapsable cell under mouse.
+ * validRoot - Exactly one cell which is a possible root under mouse.
+ * swimlane - Exactly one cell which is a swimlane under mouse.
+ *
+ * Example:
+ *
+ * To add a new item for a given action to the popupmenu:
+ * 
+ * (code)
+ * <mxDefaultPopupMenu as="popupHandler">
+ *   <add as="delete" action="delete" icon="images/delete.gif" if="cell"/>
+ * </mxDefaultPopupMenu>
+ * (end)
+ * 
+ * To add a new item for a custom function:
+ * 
+ * (code)
+ * <mxDefaultPopupMenu as="popupHandler">
+ *   <add as="action1"><![CDATA[
+ *		function (editor, cell, evt)
+ *		{
+ *			editor.execute('action1', cell, 'myArg');
+ *		}
+ *   ]]></add>
+ * </mxDefaultPopupMenu>
+ * (end)
+ * 
+ * The above example invokes action1 with an additional third argument via
+ * the editor instance. The third argument is passed to the function that
+ * defines action1. If the add-node has no action-attribute, then only the
+ * function defined in the text content is executed, otherwise first the
+ * function and then the action defined in the action-attribute is
+ * executed. The function in the text content has 3 arguments, namely the
+ * <mxEditor> instance, the <mxCell> instance under the mouse, and the
+ * native mouse event.
+ *
+ * Custom Conditions:
+ *
+ * To add a new condition for popupmenu items:
+ *  
+ * (code)
+ * <condition name="condition1"><![CDATA[
+ *   function (editor, cell, evt)
+ *   {
+ *     return cell != null;
+ *   }
+ * ]]></condition>
+ * (end)
+ * 
+ * The new condition can then be used in any item as follows:
+ * 
+ * (code)
+ * <add as="action1" action="action1" icon="action1.gif" if="condition1"/>
+ * (end)
+ * 
+ * The order in which the items and conditions appear is not significant as
+ * all connditions are evaluated before any items are created.
+ * 
+ * Parameters:
+ *
+ * editor - Enclosing <mxEditor> instance.
+ * menu - <mxPopupMenu> that is used for adding items and separators.
+ * cell - Optional <mxCell> which is under the mousepointer.
+ * evt - Optional mouse event which triggered the menu.
