 - Use binary read/write table to save storage space and read in times (Mark's suggestion)
   (Not clear that binary storage actually saves anything ...! Test first.)
 - Provide features to allow -> APPLgrid conversion and the inverse -> fastNLO
-- Test installation with lgcenv environment
-   - Problem with zlib?
-   - Problem with HOPPET?
 - Streamline usage of logger.messagelevel, shout|cout, error|warn|silent etc. in speaker
 - Getter for PhaseSpace-check: a la: GetIsWithinPhaseSpace(double obs1, double obs2, etc.) (cache probably observables for later usage)
 - Write documentation (e.g. twiki)
