+ * It is tedious to import Java classes used in a script. Sometimes it is easier
+ * use simple names of java classes and have a script auto import Java classes. 
+ * You can load this script at the start of an interactive jjs session or at the
+ * start of your script. This script defines a __noSuchProperty__ hook to auto 
+ * import Java classes as needed and when they are referred to for the first time
+ * in your script. You can also call the "autoimports" function to print script 
+ * statements that you need to use in your script, i.e., have the function generate
+ * a script to import Java classes used by your script so far. After running your
+ * script, you can call autoimports to get the exact Java imports you need and replace
+ * the autoimports load with the generated import statements (to avoid costly init of
+ * the autoimports script).
