lencodJM20Original.exe  ---- full integer search
lencodJM20Dyna.exe      ---- integer search with dynamic range decision
lencodJM20Fast.exe      ---- integer search with fast algorithm proposed by tsinghua
lencodJM20FastDyna.exe  ---- integer search with fast algorithm proposed by tsinghua plus dynamic search

============================================================
1. if add "Fast_Integer" in preprocessor definiation:
   the integer motion  estimation will use our algorithm, but only  16x16 search mode is 
   supported now(other mode will be supported soon :) )

2.  if add "_RANGE_DECISION" in preprocessor definiation:
 Dynamic search range algorithm as D117 described is used.

3. these  two algorithms can be used together.

=============================================================
Each line of the batch file is like the following format:
lencodx 
-p InputFile=Foreman[30fps].qcif
-p SourceWidth=176
-p SourceHeight=144
-p QPFirstFrame=16
-p QPRemainingFrame=16
-p FrameSkip=2
-p FramesToBeEncoded=101
lencodx means one of the motion estimation scheme, -p set other parameter.
We change different 4 lencodx and 4 different sequences and 4 different QP
(Totally 64 times running) and get the result.
