The removal of this plugin originates the errors in the HI simulation workflows (140.0, 141.0, 143.0, 300.0, 301.0, 302.0) as in 
https://cmssdt.cern.ch/SDT/cgi-bin//showMatrixTestLogs.py/slc6_amd64_gcc481/www/sat/7.0-sat-02/CMSSW_7_0_X_2013-12-07-0200/pyRelValMatrixLogs/run/
Please fix either by putting back the plugin, or modifying also the HI validation.
