+ * FieldVerifier validates that the name the user enters is valid.

+ * <p>
+ * This class is in the <code>shared</code> packing because we use it in both
+ * the client code and on the server. On the client, we verify that the name is
+ * valid before sending an RPC request so the user doesn't have to wait for a
+ * network round trip to get feedback. On the server, we verify that the name is
+ * correct to ensure that the input is correct regardless of where the RPC
+ * originates.
+ * </p>
+ * <p>
+ * When creating a class that is used on both the client and the server, be sure
+ * that all code is translatable and does not use native JavaScript. Code that
+ * is note translatable (such as code that interacts with a database or the file
+ * system) cannot be compiled into client side JavaScript. Code that uses native
+ * JavaScript (such as Widgets) cannot be run on the server.
