24  \class CClientServerMappingDistributed
25  This class computes index of data which are sent to server as well as index of data
26on server side with a distributed alogrithm. Each client has a piece of information about the distribution
27of servers. To find out all these info, first of all, all client join a discovering process in which each client
28announces the others about the info they have as well as demand others info they are lacked of. After this process,
29each client has enough info to decide to which client it need to send a demand for corresponding server of a global index.
30The alogrithm depends on hashed index.
