Trying to root and install Xposed on Nexus 5 with Lollipop
Hopefully I don't get burned too badly for this, but I thought I would share this info for people who haven't rooted/unlocked their phones lately (or never have). 

In order to root one must unlock first; this functionality is provided in Wug's rootkit as well as the rooting function.

I was trying to mod my phone as little as possible, and I was told by several people that I could root without unlocking first, but it appears that this can never be done (perhaps Wug's rootkit should make that a pop up notification that the user must read in case a scenario presents itself where a user tries doing what I did; this way they can take recourse). In short, I had heard long ago that rooting and/or unlocking could potentially permanently disable Google Wallet, (more deeply speaking, I believe it would disable the use of the NFC chip) and I use NFC for lots of things so I didn't want to risk it if I didn't have to. 

I've restored now, and everything has been tested and is fully functional.
