outputting multiple \books

As you can easily see when looking at the definition of \bookOutputName and  
\bookOutputSuffix, they don't use a parser variable but rather a global  
variable.  There is no nesting of \book blocks here, like \context {  
\Score ... } is not a nesting of context definitions.  It is just a syntax  
for referring to an existing \book definition, and you can't use a book  
variable anywhere but at the top of a \book block.

The whole point of the original poster was that the outputname can be  
changed in midsession.  So it is perfectly sensible to store it in a book  
definition.  The question is just where.  The \paper output definition  
makes sense to me.  That is not an absolute: I am certainly open to better  
suggestions.

A global variable does not make sense to me.  That's what we have now.
