/**
 * Declare a plugin property. Values are available at runtime through the component {@link Settings}.
 * 

* It's the programmatic alternative to the annotation {@link org.sonar.api.Property}. It is more * testable and adds new features like sub-categories and ordering. *

* Example: *

 *   public class MyPlugin extends SonarPlugin {
 *     public List getExtensions() {
 *       return Arrays.asList(
 *         PropertyDefinition.builder("sonar.foo").name("Foo").build(),
 *         PropertyDefinition.builder("sonar.bar").name("Bar").defaultValue("123").type(PropertyType.INTEGER).build()
 *       );
 *     }
 *   }
