-Next, we implement our event through a `DiscreteCallback`. It triggers every 12 time units, and when it does, it flips the value of `l`. Since we will interface with $l$'s value multiple times, we [create specific `getl` and `setl` functions](@ref simulation_structure_interfacing_functions) to do this (in practice, due to this model's small size, the performance impact is negliable).
