Set the parent action that cause new dispatch in reactions

[fabienjuif]

So it is easier to debug.

{
  type: 'NEW_ACTION_FROM_REACTON', 
  payload: 'reaction payload',
  parent: {
    type: '@@krml/INIT'
  }
}

• I can't use middlewares
• I can't use my own dispatch middleware to set parent then run reactions, because of async reaction
• So I have this in mind right know
  • This is close to Add a reset store function #72 (comment)

  // 1. Attach { getState, dispatch } to each krf reducers
  // 2. krf reducers "toContext" use that instead of given store
  // 3. Have a function to set new { getState, dispatch } to each krf reducers
  // 4. Use this to set store the first time
  // 5. Have a function to clone the reducer tree (each krf) given a the store (clone the store)
  //      /!\ Take care, it should not clone the store (redux one)
  // 6. In listener middleware
  //   a. Clone the store (with all krf reducer cloned)
  //   b. Set the new { getState, dispatch } with enhanced dispatch
  //   c. Pass the new "store" to reactions
  /* const keys = [...Object.keys(reduxStore), 'listeners']
  const reducerTreeKeys = Object.keys(store).filter(key => !keys.includes(key))
  console.log(Object.keys(store.config)) */

I close this issue since trace option exists on redux-devtools.
