added code to show all possible lcs permutations
Show actual mapping along with the lcs (actual index to index mapping)
Merge branch 'characterModel' into plcs
made lcs plcs
Modify to return the probability with LCS, handle those mappings which don't exist in the CEM, added minProb to CEM to ignore 0 mutiplication problem i.e. applied smoothing
add common functions to utilities.py
Merge branch 'plcs' into pld
Modify to take use of utilities.py
