/**
 * This class is a replacement for the SelfExtractor that provides a similar
 * function to the SelfExtractor but avoids the need to extract all the
 * files prior to running the build.  When using this extractor the project
 * is run from the Jar but It is the Ant builds responsibility to access
 * resources from within the Jar the Jar itself can be referenced using 
 * the Ant property "antinstaller.jar".  The build file is automatically read
 * from the Jar.
