A bitvector implemented with Packed SIMD 2.
let mut bitvec = BitVector::ones(1000); // create a bitvector contains 0 ..= 999
bitvec.set(900, false); // delete 900 from bitvector
bitvec.set(1200, true); // add 1200 to bitvector (and expand bitvector to length 1201)
let bitvec2 = BitVector::ones(1000);
let new_bitvec = bitvec.and_cloned(&bitvec2); // and operation, without consume
let new_bitvec2 = bitvec & bitvec2; // and operation, consume both bitvector
// Operation Supported:
// and, or, xor, not, eq, eq_left
