Layered Cherry Cake

Description
This is a quick recipe that I got from a family cookbook. It seemed a little unusual to me at first, but it was a big hit with my DH! I like to use pecans in this, but you could use just about any nut. I like to chop the nuts, but you don't have to. I also typically don't use the whole can of pineapple.
