Ever been or heard of an atheist burial?

My friend's grandma passed away just recently and they're coordinating her burial/funeral services but it's going to be non-religious. When she was alive, she made it clear about not wanting anything to do with god and religion at all. She was hardcore atheist all the way to her deathbed.

Ever been or heard of atheist burial/funerals? What are they like?
