Arbitrary size bitvectors

Could this library support arbitrary sized bitvectors? Suppose i have two 32bits vectors, I could store them in an unsigned integer of 32 bits. But if I have bitvectors of 1200 bits it would be ideal to break them up into 2x512 bits and one 256 bit (using the remaining 176 needed bits). I would like to perform simple operations such as AND, OR, NOT and arithmetics like + and -
