subroutine EULER(Z, XX, IFACE, TOLEULER)
@# KKRtags: VORONOI geometry
GIVEN TWO DISTINCT POINTS (Z(1),Z(2),Z(3)) AND (XX(1),XX(2),XX(3))
THIS ROUTINE DEFINES A LOCAL COORDINATE SYSTEM WITH THE Z- AXIS
PASSING THROUGH (Z(1),Z(2),Z(3)) AND THE X- AXIS PARALLEL TO THE
VECTOR : (XX(1)-Z(1),XX(2)-Z(2),XX(3)-Z(3)).
THE EULER ANGLES ROTATING THIS LOCAL COORDINATE SYSTEM BACK TO THE
ORIGINAL FRAME OF REFERENCE ARE CALCULATED AND STORED IN COMMON.
