// class G4LogicalCrystalVolume
//
// Class description:
//
// Specialised logical volume for the description of crystals.
// The object can be created only with an extended material
// with a crystal extension. The class handles the orientation
// of the crystal axes wrt the solid to which the crystal is attached.
//

// History:
//
// 21-04-16, created by E.Bagli
