[boost] typeof emulation internals

Hi all, While the work is being done to incorporate the latest MSVC-specific typeof trick under the proposed BOOST_TYPEOF umbrella, I would like to take one step back and offer a document that describes the internals of the typeof emulation. The document is related to so-called "compliant" implementation as opposed to Peder's "vintage" implementation. So, if anybody is interested, please take a look at typeof_internals.htm.zip in the Boost Sandbox File Vault, http://boost-sandbox.sourceforge.net/vault/. As always, any comments/suggestions are welcome. Regards, Arkadiy
