Composite activation function

[hovsep]

we can have some helper api for cases like this:

WithActivationFunc(func(this *component.Component) error {
			brainErr := handleBrainSignals(this)
			if brainErr != nil {
				return brainErr
			}

			heartErr := handleHeartSignals(this)
			if heartErr != nil {
				return heartErr
			}

			return nil
		})

Something like: WithActivationFunc(component.CompositeActivationFunction(doThis, thenThis, andThis))

Also we can think about different error handling strategies within the composition: fail on first or do all and return resulting error
