> Looks like the RangeEqualsVisitor's logic to BaseFixedWidthVectors doesn't work for BitVector because the typeWidth of BitVector is 0.
> Here is the example.
> {code:java}
> try (final BitVector vector1 = new BitVector("bit", allocator);
>     final BitVector vector2 = new BitVector("bit", allocator)) {
>   setVector(vector1, 0, 1, 0);
>   setVector(vector2, 1, 1, 0);
>   VectorEqualsVisitor visitor = new VectorEqualsVisitor();
>   // Fail here
>   assertFalse(visitor.vectorEquals(vector1, vector2));
>   vector1.set(0, 1);
>   assertTrue(visitor.vectorEquals(vector1, vector2));
> } {code}
