Schutz' Independent Axioms for Minkowski Spacetime

This is a formalisation of Schutz' system of axioms for Minkowski spacetime published under the name "Independent axioms for Minkowski space-time" in 1997, as well as most of the results in the third chapter ("Temporal Order on a Path") of the above monograph. Many results are proven here that cannot be found in Schutz, either preceding the theorem they are needed for, or within their own thematic section.
