define-session-public commands

To expound on comment #11: supported-clefs should likely not be exported.   
Instead, a function for doing the reverse lookup should be written in the  
same file, and this function will do the memoization and choice of data  
structure (again not exported) itself.  Then you export this accessor  
function, and that is what is getting used elsewhere.
