/**
* A meet-semilattice (or lower semilattice) is a semilattice whose operation is called `meet`, and which can be thought
* of as a greatest lower bound.
*
* A `MeetSemilattice` must satisfy the following laws:
*
* - Associativity: `a ∧ (b ∧ c) <-> (a ∧ b) ∧ c`
* - Commutativity: `a ∧ b <-> b ∧ a`
* - Idempotency: `a ∧ a <-> a`
