/**
* This example program shows how to reade/write the ITK object itk::ParticleSwarmOptimizer using
* the traditional SAX-based API and the newly introduced DOM-based API.
*
* The program reads a PSO XML file (arg1) using both DOM-based and SAX-based readers, then
* writes out the loaded PSO object using both DOM-based (arg2) and SAX-based (arg3) writers.
*
* Please see [ITK_HOME]/Testing/Data/InputXML/test.pso.xml for an example XML file for the PSO object.
