Api/changes

@oalders : I have made all the changes to the scripts in this pull requests. And tidied everything.

Please have a look at it.
It's now possible to get the Pod in one request rather than in two (which this example does).  Please see https://metacpan.org/pod/MetaCPAN::Client::Pod  This isn't your fault -- it just recently got merged, but I think it's the best way to handle this particular case.
