This reads a CD's table of contents (TOC) and calculates the MusicBrainz
DiscID, which is a 28 character ASCII string. This DiscID can be used
to retrieve a list of matching releases from the web service (see
L{musicbrainz2.webservice.Query}).
Note that an Audio CD has to be in drive for this to work. The
C{deviceName} argument may be used to set the device. The default
depends on the operating system (on linux, it's C{'/dev/cdrom'}).
No network connection is needed for this function.
If the device doesn't exist or there's no valid Audio CD in the drive,
a L{DiscError} exception is raised.
