/*
 * The changes to this class include:
 * the render code will now use glDrawElementsInstanced;
 * there is a setInstances method that allows us to set the different model matrices;
 * we no longer need getModelMatrix(), so it has been removed;
 * there is a new field numMeshes that indicates the number of instances;
 * we no longer store the individual positions for this example, so that has been removed too
