Theorem tsmsxp 24103

Description: Write a sum over a two-dimensional region as a double sum. This infinite group sum version of gsumxp 19943 is also known as Fubini's theorem. The converse is not necessarily true without additional assumptions. See tsmsxplem1 24101 for the main proof; this part mostly sets up the local assumptions.
