                   SPURIOUSZERO

This is a special class used to consume the spurious zero in some p_brew.listfileresponse

The three bytes are formatted as follows:

An optional 'null' byte (this class)
A byte specifying how long the directory name portion is, including trailing slash
A byte specifying the length of the whole name
The bytes of the filename (which includes the full directory name)

Fun and games ensue because files in the root directory have a zero length directory name, so we have some heuristics to try and distinguish if the first byte is the spurious zero or not

Also allow for zero length filenames.

	`autologwrite(self, buf, logtitle)`
	`getvalue(self)` Returns our underlying value if sensible (eg an integer, string or list) else returns self
	`iscontainer(self)` Do we contain fields?
	`packetsize(self)` Returns size in bytes that we occupy
	`packetspan(self)` Returns tuple of begining,end offsets from last packet we were read or written from.
	`update(self, args, *kwargs)`
	`writetobuffer(self, buf)` Scribble ourselves to the buf
	`_complainaboutunusedargs(self, klass, dict)` A helper function that will raise an exception if there are unused keyword arguments.
	`_consumekw(self, dict, consumelist)` A helper function for easily setting internal values from the dict
	`_ismostderived(self, klass)`
Inherited from object
	`__delattr__(...)` x.__delattr__('name') <==> del x.name
