/// Straightforward implementation for the proxy class
/**
  * This is a straightforward 1-to-1 proxy implementation assuming
  * that there is a simple translation from a persistent class
  * to a transient one.
  *
  * The proxy class is parametrized by mean of one template parameter:
  *
  *   T - is a transient class representing a proxy product
  *
  * This proxy is using the "persistent-to-transient" translation facility
  * of the CDB API in order to get the transient product. The corresponding
  * converter must be registered with a CDB API implementation used in an application
  * context where an instance of the current proxy is being used.
  *
  * @see class CdbObjectTranslator
