makeZeroMackeyFunctor -- constructs the zero Mackey functor for the group

Usage:

makeZeroMackeyFunctor(p)
Inputs:
- p, an integer, a prime number $p$
Outputs:
- a C_p Mackey Functor, the zero Mackey functor for $C_p$

Description

Perhaps the easiest Mackey functor is the zero Mackey functor which has the zero-module as both the underlying and fixed modules. This is the zero object in the abelian category of Mackey functors, and is therefore important to implement for homological algebra computations.
