Shell script that can convert the zipf debug files from iMSG to pdf rendered frequency graphs
Added option to get zipf debug information , which is basically two files containing all occurences of either propertyformula predicates or relationformula predicates
Merge remote-tracking branch 'origin/master'
Removed debug statements, should get better solution
1) Renamed zipf to stat to make more general
2) Added statistics on grammar sizes, grammar costs and parse costs to an output file
