Add fuselage structure to massBreakdown

[rmaierl]

The recently added feature of the fuselage walls would require an additional representation in the massBreakdown.

Please find attached the schema snippet of the cpacs node:
/cpacs/vehicles/aircraft/model/analysis/massBreakdown/mOEM/mEM/mStructure/mFuselageStructure

and

/cpacs/vehicles/aircraft/model/analysis/massBreakdown/mOEM/mEM/mStructure/mFuselageStructure/mWalls
