// 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.
