Work in Progress (version 0.1.0 in test).

Description

• The PID cache service is a client to the GWDG PID Handle Service.
• The PID cache service is used as an alternative to the PIDManager service offered by eSciDoc core infrastructure (PID Service without pre-cached PIDs).
• The PID cache service holds pre-created PIDs which are assigned to an eSciDoc content resource by calling the Item/Container Handler methods (assignObjectPid(), assignVersionPid() or assignContentPid()).
