## Annotation Type Field

-     @Documented
      @Retention(value=SOURCE)
      @Target(value=LOCAL_VARIABLE)
      public @interface Field

  Variable annotation used for changing the scope of a variable within a script from being within the run method of the script to being at the class level for the script.

  The annotated variable will become a private field of the script class. The type of the field will be the same as the type of the variable. Example usage:

       @Field List awe = [1, 2, 3]
       def awesum() { awe.sum() }
       assert awesum() == 6

  In this example, without the annotation, variable `awe` would be a local script variable (technically speaking it will be a local variable within the `run` method of the script class). Such a local variable would not be visible inside the `awesum` method. With the annotation, `awe` becomes a private List field in the script class and is visible within the `awesum` method.
