Please add an efficient IPv6AddressRange.size()

[GoogleCodeExporter]

Please add an efficient size method to the IPv6AddressRange class?
The current inefficient workaround is to iterate the range and count.
Thanks.

Good idea, I'll look into it.

size() method added.

Note that you can use the implementation (using BigInteger) as inspiration for 
a more efficient workaround in your code while awaiting a new release of the 
java-ipv6 library.

    public BigInteger size()
    {
        BigInteger firstAsBigInteger = new BigInteger(1, first.toByteArray());
        BigInteger lastAsBigInteger = new BigInteger(1, last.toByteArray());

        // note that first and last are included in the range.
        return lastAsBigInteger.subtract(firstAsBigInteger).add(BigInteger.ONE);
    }
