(*) Added array subscript operators for vector and matrix types in
C++. This is provided as a convenience, but be aware that it may
incur an extra function call in unoptimized builds.

(*) Renamed the 'Rows' member of hmm_mat4 to 'Columns'. Since our
matrices are column-major, this should have been named 'Columns'
from the start. 'Rows' is still present, but has been deprecated.
