[TYPO3-50-general] Refactoring-help needed

[Bastian Waidelich]

Hi all of you infamous PHP developer ;)

While implementing "optional Route Parts" 
(http://forge.typo3.org/issues/show/1790) to the FLOW3 Routing mechanism 
my brain is starting to curl and I'm a bit stuck.
Well, the code works but it's quite chaotic now and basically unreadable.

Anyone fancy refactoring this

Any help is welcome!

Have a nice weekend,
Bastian
