* @brief Condition algorithm to provide the L1 trigger menu
* The algorithm will provide the menu configuration through a conditions handle using \c TrigConf::L1Menu to present the data
* It is able to load the configuration in the following 3 ways
* * File-based menu description: for most test environments: for test jobs with no database involved
* * DB-based menu description where the DB keys are provided as algorithm job-properties: for reprocessing grid jobs with new menus
* * DB-based menu description where the DB keys are taken from COOL: for offline reconstruction jobs
