        Description:

        An example context to allow remapping vertex/edge lists from one mesh to another

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

        The meshRemapContext can be created with the
        following mel commands:

                meshRemapContext;       
                setToolTo meshRemapContext1;

        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 source mesh, and the corresponding 3 vertices on 
        the target mesh. Once all 6 vertices are selected the meshRemap command will be invoked
        to remap the target mesh's vertices.
