Support for iterable type

[potasiyam]

I ran phpdox for a Symfony 4.3 project, got an error for src/Kernel.php, "Unexpected return type definition PhpParser\Node\Identifier [UnitCollectingVisitor.php:299]". Symfony 4.3 uses strict return types now. Only suspicious return type on the file was 'iterable'. Seems like phpdox's UnitCollectingVisitor->processMethodReturnType() doesn't handle the 'iterable' types. PHP Manual for Iterable type

I may have run into the same issue, certainly a similar one, on the same line in UnitCollectingVisitor.php.

$ git clone [email protected]:sebastianbergmann/phpunit.git
$ cd phpunit
$ ant generate-project-documentation

Can you try with master ?

I run a quick test with master and release 0.12.0, on master I don't have the issue, but I have it on 0.12.0
