SummationFilter.HasSupport

Typeclass asserting that the sets in L.filter are eventually contained in L.support. This is a sufficient condition for L-summation to behave well on finitely-supported functions: every finitely-supported f is L-summable with the sum ∑ᶠ x ∈ L.support, f x (and similarly for products).
