wevbarker/Hamilcar: Hamilcar v 1.0.0

Admits arbitrary tensorial field theories in 3+1 dimensions. Admits field theory on flat spacetime, or a dynamical metric for gravity. Keeps track of canonical fields and their conjugate momenta. Computes Poisson brackets between canonical quantities. Re-expresses computed brackets in terms of index-free ansätze using integrations by parts and dimensionally dependent identities. Can be used by humans. Can be used by agents. Full Changelog: https://github.com/wevbarker/Hamilcar/commits/v1.0.0
