Log::Message is a generic message storage mechanism. It allows you to store
messages on a stack -- either shared or private -- and assign meta-data to
it. Some meta-data will automatically be added for you, like a timestamp
and a stack trace, but some can be filled in by the user, like a tag by
which to identify it or group it, and a level at which to handle the
message (for example, log it, or die with it)

Log::Message also provides a powerful way of searching through items by
regexes on messages, tags and level.
