NSW Simulation - MM fixes and adjustments

Cumulative MR to fix a few things (mainly the first bullet) and to adjust other ones on the MM side:

• Fixed the way how RDO segments are built, making the procedure only if the input is in the allowed ranges
• Moved all the include instances in the header file for the MMTriggerTool class
• Changed to the default destructor for the same class
• Values passed by reference in the TriggerProcessorTool class, avoiding the copy operation
• Removed all the using instances and used the std:: namespace where needed
• Big cleanup of empty and not used branches
