def control_behavior
  # define a default nil control behavior so we can omit it when not needed
end

#key_for(source, seed = name) ⇒ Object

Deprecated.

This is deprecated logic as of v0.6.0 and should eventually be removed, but needs to stay intact for actively running experiments. The new strategy utilizes Digest::SHA2, a secret seed, and generates a 64-byte string.
