This class has several optional parameters for initialisation, which may
be used to influence the behaviour of the object:
The optional parameter `progress` is a CdromProgress() subclass, which will
ask for the correct cdrom, etc. If not specified or None, a CdromProgress()
object will be used.
The optional parameter `mountpoint` may be used to specify an alternative
mountpoint.
If the optional parameter `nomount` is True, the cdroms will not be
mounted. This is the default behaviour.
