I prefer this name over the two others.

Other suggestions:

* DMCellComplex - a bit lengthy, but expressive. Four additional letters

* DMCellSpace - a CW complex is a class of spaces, but a user usually 
refers to a particular space. It's only two more letters than DMComplex.

Furthermore, is 'DM' sufficiently expressive? I know that there is a 
whole family of DM*-functionality, but if we change the name of 
something as fundamental as DMComplex, then one can also think about 
adjusting the prefix as well (if required)...

Best regards and happy new year,
