MDB_DataExchanger is a class that allow user to exchange
data's between partitions and/or periodic boundaries. User
has to provide a tag for non synchronous communications.
Basically, choose a tag that is higher that 200 for being
sure that it does not interact with internal messages.
User has to allocate buffers using malloc.
User will receive its datas.
