/**
 * Marker annotation that can be used to define a non-static
 * method as a "setter" or "getter" for a logical property
 * (depending on its signature),
 * or non-static object field to be used (serialized, deserialized) as
 * a logical property.
 *
 * Default value ("") indicates that the field name is used
 * as the property name without any modifications, but it
 * can be specified to non-empty value to specify different
 * name. Property name refers to name used externally, as
 * the field name in Json objects.
 *

 * NOTE: since version 1.1, annotation has also been applicable
 * to fields (not with 1.0).
 *
 * NOTE: since version 1.2, annotation has also been applicable
