`SimpleCompletionPolicy` should have `getChunkSize()` method.

[MinJunKweon]

Currently, SimpleCompletionPolicy doesn't have getChunkSize().
But toString() method returns a string that include own chunk size by some format.

You can see them on this.

SimpleCompletionPolicy examplePolicy = new SimpleCompletionPolicy(50);
System.out.println(examplePolicy.toString());
// SimpleCompletionPolicy: chunkSize=50

I think it is a code smell.
If I want to get its chunk size, I have to parse toString() result. It is a very ugly way.

I suggest two options to solve this.

1. Make toString() doesn't show own chunk size.
2. Make getChunkSize() public method.

In my opinion, It should be second option.
If you approve this idea, comment, please. And then, I will make a pull request for this.

Thank you.

I have same problem.

I'm parsing chunkSize using toString(). I know this is a bad way.
I'm worried that there will be an error if the toString() format is changed even a little.

I think the getChunkSize() should be a public method.

I agree that problem.

So, I think getChunkSize() is good suggestion.

There is already a setter for chunkSize, I see no harm in adding a getter as well.
