[JEXL] Implement short-circuit boolean evaluation

           Summary: [JEXL] Implement short-circuit boolean evaluation
           Product: Commons
           Version: Nightly Builds
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Enhancement
          Priority: Other
         Component: JEXL
        AssignedTo: [EMAIL PROTECTED]
        ReportedBy: [EMAIL PROTECTED]


The current implementation of ASTAndNode and ASTOrNode will evaluation both 
sides of an expression before returning a result.  I think most developers 
these days seem to expect the RHS of an AND/OR expression to be ignored if the 
LHS is sufficient to determine the result 
(e.g. if A=>true, "A or B"=>true, regardless of B).

The patches appear to be trivial - if a committer is interested & thinks it 
worthwhile I'll create them.

(btw, the old Turbo Pascal compiler described this optimisation as "short 
circuit boolean evaluation"; I'm not sure if that is a common name for it.)
