Quickoffice HD?

[Jeremy]

Is Quickoffice HD (not Pro HD, just HD) part of gapps now? I've been using my tablet for light office tasks lately, and it keeps asking me which app I'd like to use. I have Kingsoft Office installed and generally prefer it. I can't find any reference to Quickoffice HD anywhere. It doesn't show up under installed apps in the Google Play Store, it's not in the launcher, and it doesn't show up when I look under settings:apps:downloaded. It does show under settings:apps:all. Where did this app come from? Is it part Drive?

I know I can just set up Kingsoft Office to open all my office related documents if I want, but I'm curious as to where this extra app that I can't seem to find came from.
