abstract int fold(int hash,
                  int bits)
```
    Fold the given 32-bit hash code into only bits of space.
    
    Parameters:
    
    hash - the 32 bit hash code to be folded into a smaller value.
    
    bits - total number of bits that can appear in the output. The output value must be in the range [0, 1 << bits). When bits = 2, valid outputs are 0, 1, 2, 3.
    
    Returns:
    
    the folded hash, squeezed into only bits.
