/** @class BooleConstant
* @brief This class wraps a bool value, which was not converted to a boolean
* polynomial or monomial yet.
*
* This is mostly equivalent to the built-in type @c bool. Only conversion
* from integer values to @c BooleConstant is nontrivial, as it involves the
* modulo 2 operation.
*
* The class partially implements the interfaces of @c BoolePolynomial and
* @c BooleMonomial.
*
* @note Since BooleConstant(1) may be interpreted as monomial as well as
* polynomial, we skip member functions, that have different meanings for
* polynomials and monomials (like begin() and end()).
