[Chimera-users] Subclass chimera.Molecule

Oh, I see. I am not familiar with wrappers and those "nasty" things, but I
do guess they're a nightmare to deal with!
For now, I will stick with a dirty workaround I figured out last night. The
molecule itself will be an attribute of the Compound, so it is now
available as `Compound.m`. Not perfect, but close :)
Thanks for the help!
