Avoid creating repetitive logical volumes for sampling calorimeters

[veprbl]

Ideally, you create the logical layer volume once and place it several times. The flow would be:

• Create logical layer volume
• Loop over slices
  • Create logical slice volume
  • Place logical slice volume inside logical layer volume
• Loop over layers
  • Place logical layer volume in the logical envelope volume
• Place logical envelope volume in the detector's mother volume
