// This class builds the Services as Cylinders
//
// The services are grouped in 4 groups (as in G3)
// I keep this grouping as it natural in the database.
// They are Barrel-Inside tracking volume
//          Barrel-Outside tracking volume
//          Endcap-Inside tracking volume
//          Edncap-Outside tracking volume
//
// The elements for each group are defined in initialize,
// with Barrel/endcap coming from the geometry manager and inside outside,
// from the mother volume name.
// This class builds the n-th  service element, with n defined in SetCylinder
//
//
//
// The information on which layer to build is retrieved by the Geometry Manager
//
// Contained by: passed by argument
//
// Contains: nothing
//
// The services support several different shapes. The meaning of the parameters 
// depends on the particular shape: 
// 
// 
// TUBE or empty
//   Ignored: RIN2,ROUT2,PHI,WIDTH,REPEAT
// TUBS
//   Ignored: RIN2,ROUT2
//   PHI: phi start location of tube sector
//   WIDTH (Gaudi::Units::deg): phi width of sector  
//   REPEAT: Repeat the tube sector this many times in phi with equal distance between them.
// CONS, CONE
//   WIDTH,REPEAT ignored if CONE
//   RIN2,ROUT2: rmin, rmx at zmax. Same as RIN, ROUT if <=0.
//   PHI, WIDTH, REPEAT same as TUBS    
// PGON
//   Ignored: WIDTH
//   RIN,ROUT,RIN2,ROUT2 defined at corner of polygon.
//   PHI: phi start location of a corner
//   REPEAT: Sides of polygon
// PGON2
//   Ignored: WIDTH
//   RIN,ROUT,RIN2,ROUT2 defined at side of polygon.
//   PHI: phi start location of center of side.
//   REPEAT: Sides of polygon
// PGON3 (pgon at outer edge, circular inner edge)
//   Ignored: WIDTH
//   RIN,RIN2 radius of inner edge (tube or cone)
//   ROUT,ROUT2 defined at corner of polygon.
//   PHI: phi start location of a corner
//   REPEAT: Sides of polygon
// PGON31 (pgon at inner edge, circular outer edge)
//   Ignored: WIDTH
//   RIN,RIN2 radius of inner edge (tube or cone)
//   ROUT,ROUT2 defined at corner of polygon.
//   PHI: phi start location of a corner
//   REPEAT: Sides of polygon
// PGON2 (pgon at outer edge, circular inner edge)
//   Ignored: WIDTH
//   RIN,RIN2 radius of inner edge (tube or cone)
//   ROUTROUT2 defined at side of polygon.
//   PHI: phi start location of center of side.
//   REPEAT: Sides of polygon
// ROD
//   Ignored: ROUT, RIN2, ROUT2
//   RIN: Radial position of center of tube
//   PHI: phi position of center
//   WIDTH (Gaudi::Units::mm): diameter 
//   REPEAT: Repeat this many times in phi with equal distance between them.
// ROD2
//   Ignored: ROUT, RIN2, ROUT2
//   RIN: Radial position of center of tube
//   PHI: phi position of center
//   WIDTH (Gaudi::Units::mm): diameter 
//   REPEAT: Repeat this many times in phi with equal distance between them.
// BOX
//   Ignored: RIN2, ROUT2
//   ROUT-RIN = thickness of box (radially)
//   (RIN+ROUT)/2 = radial poistion of center of box
//   PHI: phi position of center
//   WIDTH (Gaudi::Units::mm) = width of box
//   REPEAT: Repeat this many times in phi with equal distance between them.
// TRAP
//   Ignored: RIN2, ROUT2
//   ROUT-RIN = thickness of trapezoid (radially)
//   (RIN+ROUT)/2 = radial poistion of center of trapzoid
//   PHI: phi position of center
//   WIDTH (Gaudi::Units::mm) = width of trapezoid at center
//   REPEAT: Repeat this many times in phi with equal distance between them.
//
//   **IMPORTANT NOTE** WIDTH can be in degrees or Gaudi::Units::mm. See DBPixelGeoManager
