Cylinder: ID:<ID>, dia:<diameter>, len:<length>, cl:(<x>,<y>,<z>), angle:<angle>, error:<err>% , material:<mat-name>, layer:<layer-name>, on photos used: < on photos used> unused <unused>.
• <ID> is the ID number of the Cylinder object
• <diameter> is the diameter of the computed cylinder object
• <length> is the length of the computed cylinder object
• <x>,<y>,<z> is the vector of the center line of the computed cylinder
• <angle> is the worst angle between photographs that image this cylinder (larger it better)
• <err> is the percentage error of the cylinder calculation (smaller is better)
• <mat-name> is the name of the material assigned to this cylinder
• <layer-name> is the name of the layer this cylinder is assigned to
• <on photos used> is the list of photographs the Cylinder’s mark appears on.
• <unused> is the list of unused photographs the Cylinder’s mark appears on.
