/*
        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.
