Defaults API

Breaking changes:

• actions: { action: { create () {} }} now defaults to pass the first argument through as the payload

Enhancements:

• actions: { action: { reduce () {} }} now defaults to prop assign ({...state, ...payload}) if omitted (was: Error)
• Added id = x => x utility function
• Added assign('propName') utility function to set the provided key in the state to the payload value.
• You can now replace the actions: { action } object with a function. It will be used as the reducer, assuming the default action creator behavior
• More documentation and examples
