Isodot
isodot creates a dot isosurface object from a map object.
USAGE
isodot name = map, level [,(selection) [,buffer [, state ] ] ]
map = the name of the map object to use.
level = the contour level.
selection = an atom selection about which to display the mesh with an additional "buffer" (if provided).
NOTES
If the dot isosurface object already exists, then the new dots will be appended onto the object as a new state.
