+/**
+ * Interface representing object that can locate a spring context. The implementation should take up
+ * little room when serialized.
+ * 
+ * SpringObjectLocator uses this interface to locate the spring context so that it in turn can
+ * locate a bean.
+ * 
+ * Ideal implementations use a static lookup to locate the context.
+ * 
+ * For Example:
+ * 
+ * <pre>
+ * class SpringContextLocator implements ISpringContextLocator
+ * {
+ *      public ApplicationContext getSpringContext()
+ *      {
+ *              //MyApplication is the subclass of WebApplication used by the application
+ *              return ((MyApplication)Application.get()).getContext();
+ *      }
+ * }
+ * </pre>
+ * 
+ * @see SpringBeanLocator
+ * 
+ * Based on code from Apache Wicket by Igor Vaynberg
