Slice a hash to include only the given keys. This is useful for limiting an options hash to valid keys before passing to a method:

  def search(criteria = {})
    assert_valid_keys(:mass, :velocity, :time)
  end

  search(options.slice(:mass, :velocity, :time))

If you have an array of keys you want to limit to, you should splat them:

  valid_keys = [:mass, :velocity, :time]
  search(options.slice(*valid_keys))
