Initial pull request. Filesystem_helper merging directory_helper, file_helper and path_helper.

Don't have tests because can't get vfsStream to work.

What issues are you having getting vfsStream to work? I've never actually used it but can maybe point you in the right general direction. I appreciate all of the help, but we really need tests on all of these things...

I can install vfsStream using composer, but can't instantiate none of its files. Don't know how to manage namespaces and psr-4 in this case:

_test_dir = vfsStreamWrapper::getRoot(); } ```

[lonnieezell]

Looking at the example in the wiki, you're missing the namespace for vfsstream. Outside of the class (right below the namespace declaration) you'd need to put:

use org\bovigo\vfs\vfsStream,
    org\bovigo\vfs\vfsStreamDirectory;

@Portaflex are you going to be able to do any more on this?

[Portaflex]

I can't instantiate vfsStream. Sorry. So, that's a "no".

[lonnieezell]

Even with the use statement in place? Hmmm. Alright, I'll try to take a look at it soon.
