All the definitions of `greaterThan` were `!lowerThanOrEqual`, and all the uses were implicitly assuming this semantic. However, this was confusing because in a Lattice the ordering is not total, hence `!lowerThanOrEqual` is not equivalent to `greaterThan`. This commit drops the `greaterThan` method altogether to avoid confusion.
