/*
  The Gcalc_function class objects are used to check for a binary relation.
  The relation can be constructed with the prefix notation using predicates as
        op_not (as !A)
        op_union ( A || B || C... )
        op_intersection ( A && B && C ... )
        op_symdifference ( A+B+C+... == 1 )
        op_difference ( A && !(B||C||..))
  with the calls of the add_operation(operation, n_operands) method.
  The relation is calculated over a set of shapes, that in turn have
  to be added with the add_new_shape() method. All the 'shapes' can
  be set to 0 with clear_shapes() method and single value
  can be changed with the invert_state() method.
  Then the value of the relation can be calculated with the count() method.
  Frequently used method is find_function(Gcalc_scan_iterator it) that
  iterates through the 'it' until the relation becomes TRUE.
