%description
Methods to "add" two tables; also an alternative interpretation of named
vectors as generalized tables, so that c(a=1,b=2,c=3) + c(b=3,a=-1) will
return c(b=5,c=3).  Uses 'disordR' discipline (Hankin, 2022,
<arxiv:2210.03856>). Extraction and replacement methods are provided.  The
underlying mathematical structure is the Free Abelian group, hence the
name. To cite in publications please use Hankin (2023) <arxiv:2307:13184>.
