4.2.2 bigintmat expressions

A bigintmat expression is:

1. an identifier of type bigintmat
2. a function returning bigintmat
3. a bigintmat operation involving (big-)ints and int operations (+, -, *)
4. an expression involving bigintmats and the operations (+, -, *)
5. a type cast to bigintmat (see bigintmat type cast)

Example:

  bigintmat m1[2][2]=1, 2, 6, 3;
  m1*3;
==>  3,6,
==> 18,9
  intmat im[3][2] = intmat(m1*3);
  bigintmat m2 = bigintmat(im); // cast intmat im to bigintmat
  m2;
==>  3,6,
==> 18,9
  m2*m1+m2;
==> 42,30,
==> 90,72
  _+4;
==> 46,34,
==> 94,76
