This version introduces methods for Java 8 functional-style operations.

• added stream methods for addresses, address sections, address segments, and ip address sequential ranges: stream, prefixStream, prefixStream(int prefixLength), prefixBlockStream, prefixBlockStream(int prefixLength), blockStream(int segmentCount), sequentialBlockStream, segmentsStream
• added corresponding spliterator methods: spliterator, prefixSpliterator, prefixSpliterator(int prefixLength), prefixBlockSpliterator, prefixBlockSpliterator(int prefixLength), blockSpliterator(int segmentCount), sequentialBlockSpliterator, segmentsSpliterator
• added functions to create a single stream from multiple spliterators in AddressComponentRange:
  • <T extends AddressComponent> Stream<T> stream(Function<T, Stream<? extends T>> addrStreamFunc, T ...components)
  • <T extends AddressComponent> Stream<T> stream(Function<T, Stream<? extends T>> addrStreamFunc, Collection<? extends T> components)
• added coverWithPrefixBlock method to find single covering prefix block, the smallest prefix block covering two subnets or addresses
• added IPAddressString and HostName parsed mask access through getMask method
• made sub-typing of address classes easier by loosening restrictions on using multiple network objects
• altered network mask with prefix length so that it is single host
• fixed a serialization issue involving IPAddressString instances with masks
• fixed a threading issue with IPAddressString.getDivisionGrouping
• fixed issue #32, mergeToPrefixBlocks exception on /1 prefix blocks
