A redux reducer-generator which builds a redux-reducer from a redux-reducer.

# reducer-generator-reducer

A `reducer-generator` which builds a reducer that reduces a reducer.  In most 
cases this is not useful.  It is, however, useful for libraries that are building 
reducers from various object types as it allows us to inject arguments into the 
reduction chain.

### Installation

```
yarn add reducer-generator-reducer
```

**or**

```
npm install --save reducer-generator-reducer
```

### Simple Example

```js
import createReducerReducer from 'reducer-generator-reducer'

const system = createReducerReducer(
  { /* initial state */ },
  (state, action) => {
    switch(action.type) {
      case 'SYSTEM_ONLINE': {
        return {
          ...state,
          isOnline: true
        }
      }
      case 'SYSTEM_OFFLINE': {
        return {
          ...state,
          isOnline: false
        }
      }
    }
    return state
  }, 
  /* You may pass extra args that will be passed to the reducer(s) */ 
)
```
