Data identifier

The data identifier is generated by the MA. The data identifier is a string field that contains the MA name, the number of the session plus the number of the data in the problem (incremental) plus the string ``id''. This is the id field of the diet_data_desc_t structure.

typedef struct {
  char* id;  
  diet_persistence_mode_t  mode;
  ....
} diet_data_desc_t;

For example, id.MA1.1.1 will identify the first data in the first session submitted on the Master Agent MA1.

NB:

the field ``id'' of the identifier will be next replaced by a client identifier. This is not implemented yet.
