For some complicated puzzles with multiple grips, it might be useful to
name moves based on sets of faces (i.e., URF for the vertex at the
intersection of the up, right, and front faces). If the puzzle has many
faces we may want to separate the face names with a separator to
disambiguate (say) the BL face from the B and the L face. So let's
consider allowing move base names such as U_R_F.
Such descriptive moves may be easier to manage than memorizing
yet another mapping for vertex names, especially for puzzles that
are for the most part unfamiliar.
