/**
 * Adds property declarations to generated Objective-C for annotated fields.
 *
 * See Apple's @property documentation.
 * 
 * Notes:
 * 

 *   Invalid attributes are reported as errors.
 *   readwrite, strong, and atomic attributes are removed
 *     since they are defaults.
 *   Strings will include the copy attribute.
 * 
 * 
 * Example:
 * 
 * class Foo {
 *   @Property("copy, nonatomic") protected String bar;
 * }
 * generates:
 * 
 * 
 * @property (copy, nonatomic) NSString *bar;
