    MIRROR
    Created by Sudospective
    The mirror plugin allows you to use ease and add methods
    that takes P1's mods and inverts them to P2's.
    USAGE
    Ease:
    mirror {beat, len, ease, percent, mod, mode = ease or nil}
    Add:
    mirror {beat, len, ease, percent, mod, mode = add}
    Set:
    mirror {beat, percent, mod, mode = set}
    Any mod, alias, and node is valid.
    TODO
    - Support for more than two players
    - Support for specific degree of mirror offset
    - Support for error handling
