//
// Summary:
//     Represents a collection of pages in the flow graph.
//
// Remarks:
//     A page is what contains all the elements in the flow graph. The
//     flow graph can contain many pages, each of which can contain
//     nodes, node groups and connections. A page is the first thing that
//     you must add to the flow graph, then you can add elements to the
//     pages.
