  - the material definition of the forward pixel disk's volumes using mixtures 
 @modified Xingtao Huang
  - the material definition of the forward pixel service cylinder's volumes with element description
 @modified Vesna Cuplov (october 2007)
  - update of Disks and Service cylinder materials: all the mixtures for disks were updated (added capacitors, resistors, solders  in the HDI and VHDI mixtures...
  - re-write all Service cylinder with mixture description
 @modified Vesna Cuplov (august 2008)
  -definition of Aluminium_OuterRing and Aluminium_InnerRing materials. The holes in the rings are not implemented so these are
   taken intom account in the material density.
