That's my point exactly.  The rank(2) definition was added by
Sebastian Haase who advocates the use of the term "ndims" instead of
"rank".  I've discussed the use of "dimentionality' in the preamble.
Note that ndims stands for the number of dimensions, not
dimensionality.

I don't want to remove rank(2) without hearing from Sebastian first
and I appreciate his effort to improve the glossary. Maybe we shold
add a "matrix rank" entry instead.
