Comment (by jhpalmieri):
Two more comments: "DGA" and "CDGA" are standard in the literature, but so
is "differential graded algebra" (as opposed to "differential graded
algebra").
Second, it would be very nice (for possible future implementation of
spectral sequences) to allow grading by `Z x Z`, or indeed any free
abelian group.
