/**
 * A MappingStrategy that is configured via a resource bundle.<br>
 * The resource bundle contains the script part of the url as key and the fully
 * qualified class name of the corresponding AGIScript as value.<br>
 * Example:
 * 
 * <pre>
 * leastcostdial.agi = com.example.fastagi.LeastCostDialAGIScript
 * hello.agi = com.example.fastagi.HelloAGIScript
 * </pre>
 * 
 * LeastCostDialAGIScript and HelloAGIScript must both implement the AGIScript
 * interface and have a default constructor with no parameters.<br>
 * The resource bundle (properties) file must be called
 * <code>fastagi-mapping.properties</code> and be available on the classpath.
