  * Redis protocols support

  Directory Tree
  ==================
  ./
  ./src/ 	- sources of nessDB
  ./BENCHMARK	- benchmark results of nessDB
  ./LEVEL-LRU	- nessDB's level-lru doc
  ./TODO	- nessDB's todo list
  ./x/		- nessDB's network layer(via redis),very high-performance.


  Interface
  ==========
    * db_init(int bufferpool_size,int isbgsync,uint64_t *sum)
    * db_get(const char *key)
    * db_get_range(const char *begin,const char *end,struct nobj *obj,int *retcount)
    * db_dump_keys(struct nobj *obj)
    * db_add(const char *key,const char *value)
    * db_update(const char *key,const char *value)
    * db_remove(const char *key)

    Very simple to use.

 
  How to do BENCHMARK
  ==================
	a, $cd src
	b, $make
	c, $./nessdb-bench add

	If you want to remove all indexes and datas,please use "$make cleanall" shell command.

  Start as server
  ===============
  	* $./nessdb-server
	using redis-cli(or other redis's clients) to do some operations(Now support:PING,SET,GET,DEL commands).
