Two-stop elevators

Note:This article has been removed because it was just a copy of Simple and Advanced HL2 Elevators. Despite valiant attempts, both User:Andreasen and User:MrTwoVideoCards lacked the effort to reformat it to become even close wiki standards, and User:CrabbyData promised that he was researching it, and while we wait patiently for his return, you will always have the above link to the offsite tutorial. It's better than what was on here anyway. The only reason a speedy deletion notice isn't put up, is to preserve the small talk-page. Given time, hopefully User:CrabbyData will finish the article that should be here. Below are the pictures previously linked to this article. They should probably be deleted from the wiki.
