Orthogonalization Convention

The X-PLOR orthogonalization/fractionalization convention defines $a$ in same direction as $x$; $b$ is chosen such that $y$ is in the plane defined by $a$ and $b$. This convention is used by all X-PLOR routines. To avoid difficulties when using a different convention, read the coordinates, fractionalize them according to your convention, and then orthogonalize them using the X-PLOR convention.
