/*
 * An interface class for testing if a point is within a bounding box with arbitrary orientation
 *
 * This constructor does most of the work.
 * The overall strategy is to create a box of the required size which is centered at the origin,
 * with
 * the width along the x axis, the length along the y axis, and the height along the z axis
 *
 * Then create the transformation from real space into this box, which is:
 * a translation from center to the origin, then
 * a rotation from the oriented box frame to this frame
 *
 * see OrientedBoxMarker OrientedSubdomainBoundingBox
