[boost] [endian] Request formal review

There is an update to my endian proposal available at http://mysite.verizon.net/beman/endian-0.5.zip The docs can be read online at http://mysite.verizon.net/beman/endian-0.5/libs/integer/doc/endian.html This update: * Reflects all comments received to date. * Makes the proposal part of the Boost integer library. * Docs have been updated and expanded. * Native endianness has be implemented. The proposal is mostly done at this point and is essentially ready for a formal review. --Beman PS: The stream inserters/extractors still need to be templatized, but that is a minor issue and I need to move on to other backed up proposals.
