See section 
for information about the role of administrators.
The wx:snip-admin% class is never instantiated directly. It
is not event instantiated through derived class by most programmers;
each wx:media-buffer% object creates its own
administrator. However, it may be useful to derive a new instance of
this class to display snips in a new context. Also, it may be usefull
to call the methods of an existing administrator from an owned snip.
To create a new wx:snip-admin% class, all methods described here must be overridden. They are all invoked by the administrator's snip.
Because a wx:snip-admin% object typically owns more than one snip, many methods require a wx:snip% object as a argument.
Creates an empty object.
