/*********************************************************************************
 * SVG
 *
 * Summary:	Uses the Batik library to create PNG files from SVG's.
 *
 * This task will place all generated pngs in the 'build' folder for the project;
 * which will eventually be placed in the 'resources' folder when prepDev is
 * run.
 *
 * Command Line Format: "java -cp <classpath> <batik main class> -scriptSecurityOff -m <inputDir> -d <outputDir>"
 *
 *	TODO: 	Should we have this task place the pngs in the resources folder 
 *			folder directly instead of waiting for prepDev to do it?
 *
