LANG-1402: added get methods to ArrayUtils
----
> ArrayUtils should have null and index-safe get methods.
> -------------------------------------------------------
>
> Key: LANG-1402
> URL: https://issues.apache.org/jira/browse/LANG-1402
> Project: Commons Lang
> Issue Type: New Feature
> Components: General
> Reporter: Mark Dacek
> Priority: Minor
> Original Estimate: 24h
> Remaining Estimate: 24h
>
> There should be a safe way to retrieve a value from array without having to
> check for null and length. It would be a very simple implementation but could
> save developers a great deal of time in writing and testing.
>
> Something like
>
> {code:java}
> String[] a = null;
> ArrayUtils.get(a, 5); //returns null
> a = new String[5];
> ArrayUtils.get(a, 10); // returns null
>
> a[0] = "Hello World";
> ArrayUtils.get(a, 0); // returns "Hello World"
> {code}
>
> We could handle a few other cases - a default return value. The
> tricky/annoying thing is the need to cast everything in order to make this
