addition chains in 2-NAF #147

Is is possible to generate a short addition chain with addchain taking into account the signed representation {-1,0,1} (2-NAF) of the input integer?
In some-use case (final exponentiation in the pairing computation or elliptic curve scalar multiplication), the inverse is cheap and the 2-NAF has usually lower Hamming weight.
