That's the "photo realistic" female topology from the nightly build, it's not the default mesh. It's supposed to be a high detail mesh for photo realistic renders. They have a male version too which oddly enough has no topology for nipples.
It's an ambitious program to be sure but they're hampered by the fact that the people working on it are programmers and not modellers. It had decent editing features but when it comes down to it you're editing shit.
But if you use it as a rough clay form to sculpt a proper high resolution figure from it's okay for that. That's all I ever use it for.
