/**
 * Public Singleton wrapper for the DozerBeanMapper. Only supports a single mapping file named dozerBeanMapping.xml, so
 * configuration is very limited. Instead of using the DozerBeanMapperSingletonWrapper, it is recommended that the
 * DozerBeanMapper(MapperIF) instance is configured via an IOC framework, such as Spring, with singleton property set to
 * "true"
