This is the minimal commit necessary to switch from using scala.math.Ordering to spire.algebra.PartialOrder in Predicate. This leaves other uses of scala.math.Ordering alone -- in fact we may want to switch those for spire.algebra.Order as well.
This commit completes the previous work adding PartialOrder. It also removes a bunch of unnecessary ordering constraints we had added (and instances we were capturing). It should not change how Brushfire actually works (yet).

Tests are good, but I don't think we need to flesh out the is-present stuff in this PR. Just moving |

OK, that makes sense. I'll do that next. |
This is an improvement since we have a principled way to handle the "error case" now.

This looks good to me. I do think if we are going to use spire more (and we should) we will get mileage out of the algebra work to make algebird, scalding and spire work better together. That or give up and make a |

This PR moves brushfire-core over to use
spire.algebra.PartialOrderandspire.algebra.Orderwhere applicable. At this point we don't actually use any partial orderings, but the support is there.Before we merge this I'd like to add some tests to prove this is working, and maybe flesh out support for the is present use-case a bit. What do you all think we need?
