Title: Cleanup of integrate()

Here I am cleaning up integrate(). My goal is to integrate risch_integrate() with integrate(). I am also fixing some bugs that I come across along the way. I am still working on this, and I'll add a note here when this is finished, but if tests pass, this can be merged early.
