//  Class: SoArray

//  Array group node: creates an IxJxK array. Each element in the
//  array is drawn by traversing all of the children of this node,
//  saving and restoring state before and after each element. I, J,
//  and K are given by the numElements1, numElements2, and
//  numElements3 fields. The 3D vector separating the centers of
//  adjacent elements in each of the three directions is given by
//  separation1, separation2, and separation3. The origin field
//  indicates whether the array is positioned with the current
//  object-space origin at the center of the first element, the last
//  element, or at the center of all elements.
