vfsStream 0.3.0 and good bye SimpleTest

Against my intent of starting to work on file modes for 0.3.0 I decided that it is time to get an own repository for vfsStream in order to maintain it independently from Stubbles, which was the perfect reason to open a new project on Google Code. I will see if this proves to be a good solution for day to day development.

The movement also marked the reason to try PHPUnit because I wanted to make use of its code coverage and its software metrics features. Especially the last one showed me a bunch of points that required refactoring before starting something big like supporting file modes. During refactoring some improvements made it into the code which justified a new release: vfsStream now supports rmdir(), and I made some API changes. I dropped vfsStreamDirectory::ceate() in favor of vfsStream::newDirectory() to be equivalent to vfsStream::newFile(). Additionally there is a new vfsStreamContent::at() method now, which allows to write code like this:
$parentDir = vfsStream::newDirectory('newdir')->at(vfsStreamWrapper::getRoot()); $file = vfsStream::newFile('file.txt')->withContent('foo') ->lastModified(time() - 86400) ->at($parentDir);

So far I'm very satisfied with the software analysis features of PHPUnit that I'm thinking very hard about saying good bye to SimpleTest in my other projects. Given the current state of SimpleTest's development I do not expect to get similar features in SimpleTest any time soon, and unfortunately I do not have the time to contribute to SimpleTest even if it would be a lot of fun I guess.
