Theorem tsmsxp 21768
 Description: Write a sum over a two-dimensional region as a double sum. This infinite group sum version of gsumxp 18198 is also known as Fubini's theorem. The converse is not necessarily true without additional assumptions. See tsmsxplem1 21766 for the main proof; this part mostly sets up the local assumptions.
