// Class G4QuadrangularFacet
//
// Class description:
//
// The G4QuadrangularFacet class is used for the contruction of
// G4TessellatedSolid.
// It is defined by four fVertices, which shall be in the same plane and be
// supplied in anti-clockwise order looking from the outsider of the solid
// where it belongs. Its constructor
//
// G4QuadrangularFacet (const G4ThreeVector Pt0, const G4ThreeVector vt1,
// const G4ThreeVector vt2, const G4ThreeVector vt3,
// G4FacetVertexType);
//
// takes 5 parameters to define the four fVertices:
// 1) G4FacetvertexType = "ABSOLUTE": in this case Pt0, vt1, vt2 and vt3
// are the four fVertices required in anti-clockwise order when looking
// from the outsider.
// 2) G4FacetvertexType = "RELATIVE": in this case the first vertex is Pt0,
// the second vertex is Pt0+vt, the third vertex is Pt0+vt2 and
// the fourth vertex is Pt0+vt3, in anti-clockwise order when looking
// from the outsider.
// CHANGE HISTORY
// --------------
//
// 31 October 2004, P R Truscott, QinetiQ Ltd, UK - Created.
// 12 October 2012, M Gayer, CERN, - Reviewed optimized implementation.
