further clarification of Z Notation symbols (notably glyphs 0x2119, 0x2A1F, 0x2982, 0x2A3E), by Simon Foster;

clarified \<Zcomp> (small) vs. \<Zsemi> (big);

more CONTRIBUTORS;

more Z_Notation symbols, as proposed by Simon Foster; some LaTeX-art based on tex.stackexchange "How do you make a square element symbol (\in)";

more accurate glyphs 0x25C1 / 0x25B7, based on 0x2A64 / 0x2A65 minus the "minus";

clarified order for GUI panel;

prefer more direct interpretation

more Z_Notation symbols, as proposed by Simon Foster;

more accurate spacing, according to results seen in isar-ref (Appendix B), using 12pt or 10pt;

clarified order for presentation in isar-ref (Appendix B);

prefer explicit \<Zproject> (with its own Unicode codepoint);

more Isabelle symbol definitions for Z Notation, based on https://github.com/isabelle-utp/Z_Toolkit 998c9f7880d3 by Simon Foster; NB: no bold version of 0x2900 due to fontforge crash "Internal Error: Some fragments did not join";
