- * This processor can be used on a field to return a certain function value of 
the node, if the
- * field is empty. Noticeably, this can be used on 'virtual' field, to map 
their value to a function
- * value, which can come in handy sometimes.
+ * Setter and Getter to make a virtual field which stores the actual value in 
a user's cookie.
+ * Also it can be used to store a default value for the next time a user 
creates on node of this type:
