Changes between version 0.3 and 0.4

[Bano] Added wn_synonymy as a module to match tokens when they are
synonyms of each other according to WordNet. Assumes a word in the
second string can have at most one synonym in the first string. 

[Bano] Added option --maxComputations to mStageMatcher.pl to specify
the maximum number of computations the program should perform in
looking for a solution, before aborting. If no solution is found
within the specified number of computations, the algorithm will
persist until a solution is found, and will then abort.
