 * Mark a method parameter value should be provided by

 *
 * This annotation is created because {@link javax.inject.Inject}
 * annotation cannot be applied on method parameters
 *
 * **Note** Genie does not know how to inject method parameters
 * and this annotation is provided to support framework author
 * on implementing method parameter injection. For example
 * [ActFramework](http://www.actframework.org) favor this annotation
