Note about ACTS tracking geometry construction
 
----------------------------------------------
 
 
The tracking surfaces need to be structured in a barrel + endcapP + endcapN where
 
endcapP/endcapN are the endcaps at positive/negative z values.
 
See https://acts.readthedocs.io/en/latest/plugins/dd4hep.html for more details.
 
 
The tracking geometry needs to beconstructed from cylinders from the inside out. For this reason
 
each layer needs its own subsystem assembly. This increases the number of top level system IDs.
 
For example the silicon tracker needs 3 IDs for each area (endcap+barrel+endcap) and a subassembly for each
 
layer. Therefore it needs a minimum of 20 IDs. Therefore we will allocate blocks of ~25 for each major subsystem.
 
Note, future improvements will likely include a more sophisticated ACTS-dd4hep plugin,
 
eliminating the need for so many system IDs at construction time.
 
 
This barrel/endcap structure needs IDs to be in increasing order going outward.
 
The space of IDs for the subassemblies starts at (Subassembly_ID*10+101).
 
 
The unused IDs below are saved for future use.
