/*
* positioned_tet.h
*
* The PositionedTet data structure records the position in which a
* Tetrahedron is currently being considered. The file positioned_tet.c
* contains routines for working with PositionedTets.
*
* Imagine a tetrahedron sitting on a table with one of its faces
* facing toward you. The face on the table is bottom_face and the one
* facing toward you is near_face. The faces facing away from you
* are left_face and right_face.
*
* The orientation field specifies whether the numbering on the
* tetrhedron is right_handed or left_handed when viewed in this position.
