Description of the std-file format
----------------------------------

File has to be encoded in UTF-8.
A MTC is a MTC C over the complex numbers. 

%(%...)id: identifier(s) of the MTC; first entry gives filenames: 'id'.std, etc.; rest are ids of ismorphic MTCs.

%name: one or more names of the MTC. First one is main name.

%conjugate: if of the conjugate MTC

%central_charge: the central charge of the MTC (a rational number modulo 8).

%discriminant: the discrminant of the MTC (a totally positive cyclotomic integer)

%simple: information about simple objects.
%%number: number of simple objects.
%%weights: list of conformal weights simple objects (rational numbers modulo 1).
%%qdims:  list of quantum dimensions of simple objects

%simpleorbits: information about orbits of modules under automorphism group.
%%number: number of  simple objects.
%%weights: list of conformal weights of orbits of simple objects.
%%qdims:  list of quantum dimensions of orbits of simple objects

%properties: some properties of the VOA.
- self-conjugate: equals to conjugate MTC
- unitary: has real form with positive definite invariant bilinear form.

%genera: the corresponding genera.
%%genus: one genus
%%%central_charge: the central charge of a genus.
%%%members: the ids of the VOAs of the genus.

%(%...)references: list of references.
%%ref: reference entry.
%%%author: list of authors of reference entry.
%%%title: title of reference entry.
%%%classic: classical (pre-google) description of reference entry.

%(%...)source: source of database entry.

%(%...)note: notes.
