/**
  Implements some standard methods for comparing objects. Add this mixin to
  any class you create that can compare its instances.

  You should implement the `compare()` method.

    __Required.__ You must implement this method to apply this mixin.

    Override to return the result of the comparison of the two parameters. The
    compare method should return:

    - `-1` if `a < b`
    - `0` if `a == b`
    - `1` if `a > b`

    Default implementation raises an exception.

    @param a {Object} the first object to compare
    @param b {Object} the second object to compare
    @return {Number} the result of the comparison
