Each file contains a list of GRAPE records

Extra fields:

- name = name as in the tables (or rather the label used by TeX):
    TC = Psi    ("triangular configuration");
    QC = Theta  ("quadrangular configuration");
    QF = Phi    ("quadrangular free" = pentagonal configuration)
    SC = Delta  ("star configuration" = astral)
- colourClasses = [ [ <exceptional_divisors>] ] (only if present);
                    needs a bit of work to be converted to the
                    GRAPE convention
- autGroup      = the automorphism group computed by GRAPE
- canonicalLabelling : probably useless
