Feature Smart::Comments

I renamed $status to $statuses_ref to reflect [Perl Best Practices]( http://shop.oreilly.com/product/9780596001735.do)

I have also incorporated the [Smart::Comments CPAN Module](http://search.cpan.org/~chorny/Smart-Comments-1.0.4/lib/Smart/Comments.pm) which can be enabled by removing the "#" characters at the beginning of the line below:
```
# use Smart::Comments;
```
The [Smart::Comments CPAN Module](http://search.cpan.org/~chorny/Smart-Comments-1.0.4/lib/Smart/Comments.pm) will print similar text (i.e. the example quoted below is specific to my [twitter account](https://twitter.com/cmlh)) to STDERR: 
```
### \$statuses_count is: 4023

### \$max_id is: '345706738261037056'
```
The next stage is to create a sub() to traverse the last 3200 tweets from timeline.
