+/**
+ * Class: mxCompositeLayout
+ * 
+ * Allows to compose multiple layouts into a single layout. The master layout
+ * is the layout that handles move operations if another layout than the first
+ * element in <layouts> should be used. The <master> layout is not executed as
+ * the code assumes that it is part of <layouts>.
+ * 
+ * Example:
+ * (code)
+ * var first = new mxFastOrganicLayout(graph);
+ * var second = new mxParallelEdgeLayout(graph);
+ * var layout = new mxCompositeLayout(graph, [first, second], first);
+ * layout.execute(graph.getDefaultParent());
+ * (end)
+ * 
+ * Constructor: mxCompositeLayout
+ *
+ * Constructs a new layout using the given layouts. The graph instance is
+ * required for creating the transaction that contains all layouts.
+ *
+ * Arguments:
+ * 
+ * graph - Reference to the enclosing <mxGraph>.
+ * layouts - Array of <mxGraphLayouts>.
+ * master - Optional layout that handles moves. If no layout is given then
+ * the first layout of the above array is used to handle moves.
