Metadata spec is good; unfortunately, the FCP spec hasn't been updated for
the changes to ClientGet (Pending \n URI= ... Success) and the Failed \n
Unreachable= ... EndMessage hasn't been entered either.

The Request object doesn't return metadata. It extracts certian information
(i.e. MIME type) but ignores everything else. If several MIME types are
found, only the last one is recorded.
If there's a good reason (for instance, if programs start using the metadata
field to store metadata) I'll add support to record arbitrary values
(obj.SaveMeta("Info.Description")); but in the mean-time, I'm implementing
only what I need.

See line 2 -- CFCP::Request obj(&engine);
Request (and most of the other messages) are derived from the pure virtual
Exchange class which contains DoExchange() -- that way, any object derived
from Exchange can be passed to ExchangeThread, which calls DoExchange() in a
separate thread. Convenient.
