Add handleAction example with a reducer function to README

[leonardokl]

Fixes #204

[yangmillstheory]

What do you think about pulling an example from the tests?

https://github.com/acdlite/redux-actions/blob/master/src/__tests__/handleAction-test.js

I believe most of the examples in the README are in this format.

Thanks for your time!

[leonardokl]

Ok! I updated the example with one that was in the test.

[yangmillstheory]

Can you include the expectations in the test?

[leonardokl]

I didn't get it, what kind of expectations you mean?

[yangmillstheory]

expect (...).to.equal(...)

There are similar expectations in the test, like the one bellow.

it('accepts action function as action type', () => {
  const incrementAction = createAction(type);
  const reducer = handleAction(incrementAction, (state, action) => ({
    counter: state.counter + action.payload
  }), defaultState);

  expect(reducer(prevState, incrementAction(7)))
    .to.deep.equal({
      counter: 10
    });
});

@leonardokl Will you please make new commit to resolve conflict

[mslipper]

I can just resolve them from here.

Hmm the README changed significantly since this PR was opened. I recommend closing this pr since the underlying issue that it fixes is also fixed in #222.
