new "lab_transform.m" & speed up the program "lab_align.m"

(1) speed up the program "lab_align.m" : reduce the iteration size,
amend the "A*inv(B)" to "A/B" for speed and accuracy, and delete the
csvwrite
overall speed up rate : 81sec->41sec->14sec

(2) Merge the code "lab_transform.m" to TimeVaryingDataVisualization.m"
but still have some problems (?)
