Move packages to their own files - release Pod::Tree 1.21

After fixing the use strict; use warnings; we can go back to using Perl::Critic. I ran perlcritic lib/Pod that provides some issues to be fixed.

perlcritic

The output of perlcritic lib/Pod looked like this:

Package declaration must match filename

This is usually happens when we have more than one package statements in a file. It works, but usually it is a lot more readable if every package is in its own file.

I've moved the content of package Pod::Tree::BitBucket; to the lib/Pod/Tree/BitBucket.pm and the content of package Pod::Tree::StrStream; was moved to lib/Pod/Tree/StrStream.pm. In both cases I already had use strict; and use warnings; in the package. That's what I did in the earlier, but I still had to add 1; at the end of the files to let it return true.

Instead of those I put a use Pod::Tree::BitBucket; and use Pod::Tree::StrStream; statements in the lib/Pod/Tree/HTML.pm

commit

The next step was to do the same and factoring out the package Pod::Tree::Stream; from lib/Pod/Tree.pm to lib/Pod/Tree/Stream.pm replacing it with a use Pod::Tree::Stream; statement.

commit

Then there was the separation of package Pod::Tree::HTML::PerlTop; as well.

commit.

After each such step, before committing the changes I've ran the tests and after committing the changes and pushing them out to GitHub, it has also triggered Travis-CI to build and test the code.

This, along with the decent test coverage provides me the necessary confidence to make bold changes and move forward.

perlcritic again

I ran perlcritic lib/Pod again. This time the output was much smaller:

lib/Pod/Tree.pm source OK
lib/Pod/Tree/BitBucket.pm source OK

We can go forward making changes, but I think it is also a good idea to make use of the CPAN Testers.

So I've release version 1.21.
