/*october 19, 2009-
aulit2 & aupage2 are successors to the original javascript audiopage object.
This succession amounts to a concession that the original concept ccan be implemented using basic html & javascript. Java, Flash, HTML5? even a compiled C internet client program remain possiblities for full and final implementation, 
which should also include, in time, video. 

These files make the following assumptions.
No attempt to accommodate any sound controller other than Apple's QuickTime.
The definition of a "robust" environment as a Safari browser operating in OSX.
No use of inline frames except for the robust environment.
And thus a totally "flat" implementation for non-robust environments.

Thus robust environments will call frame and poem files,
and these in turn, at least for the time being,
need the original javascript files: aulit.js & aupage.js.
Flat files need to invoke aulit2.js & aupage2.js.
Any "calling" file, index files most likely, 
that use "switchLink" need only aulit2.js I think!?
