0.0.5

Big thanks to @FreedomBen for contributing some code to fix a couple edge cases. is_ipv4/1, is_reserved/1 and is_rfc1918/1 properly handle nil input. Also added the parse_ipv4_address function which may be useful when sending ip address to Erlang functions like :gen_tcp.

0.0.4

Incorporates a change from @stevelacy to provide better validation of ipv4 strings.

0.0.3

Creating a formal release for the 0.0.3 version of iptools
