# meshReorderTool.h

    /*
            Author: Bruce Hickey

            Description:
        ------------

            An example context to allow reordering vertex/edge lists based on a user specifed seed.

            Loading and unloading:
            ----------------------

            The meshReorderContext can be created with the
            following mel commands:

                    meshReorderContext;
                    setToolTo meshReorderContext1;

            How to use:
            -----------

            Once the context has created and activated follow the help line prompts. You will
            be directed to pick 3 vertices on the mesh. Once all 3 vertices are selected the meshOrder
        command will be invoked to reorder the mesh's vertices.
