Installing Agda

I added these lines to my configuration.nixos to get a workable Agda installation:

(agda.withPackages (p: [ p.standard-library ]))

but there were a few issues, so I removed that and installed with cabal update cabal install Agda which seemed to work nicely after some hackery with zlib, and installing the standard libraries.

Owen's Geolog definitions

Owen.agda : Definitions fom Owen's first two lectures about Geolog.

These set up the basic machinery for contexts (signatures), theories and interpolation.

Compile with: agda -c --no-main Owen.agda

HoTT definitions from Martin Escardo's book "Univalent Foundations" https://arxiv.org/pdf/1911.00580

agda -c --no-main MLTT/Universe.agda

Escardo defines everything from the ground up with his own concepts of sets, universes etc., independently of the standard library.
