/*!
Make a DrawMol that does multi-coloured highlights. Both atoms and
bonds can have more than 1 highlight. There's no maximum although more
than 4 is very cluttered.
\param mol : the molecule to draw
\param legend : the legend (to be drawn under the molecule)
\param width : width (in pixels) of the rendering
set this to -1 to have the canvas size set automatically
\param height : height (in pixels) of the rendering
set this to -1 to have the canvas size set automatically
\param drawOptions : a MolDrawOptions object from the owning MolDraw2D
\param textDrawer : a DrawText object from the owning MolDraw2D
\param highlight_atom_map : indexed on atom idx, the colours to be used to
highlight atoms. Not all atoms need to be mentioned.
\param highlight_bond_map : indexed on bond idx, the colours to be used to
highlight bonds. Not all bonds need to be mentioned.
\param highlightRadii : map from atomId -> radius (in molecule coordinates)
for the radii of atomic highlights. If not provided for an atom, the default
value from \c drawOptions() will be used.
\param highlight_linewidth_multipliers : map from bondId -> int, to change
the thickness of the lines used for the highlighting.
\param confId : (optional) conformer ID to be used for atomic
coordinates
