/**
* 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;
