Removed boolean flags for enabling different specexec conflict checkers and now we have a single HStoreConf parameter 'site.specexec_scheduler_checker' that will control which one to use. Still need to integrate the conflict checkers into PartitionExecutor.finishDistributedTransaction() #132
We can now abort a dtxn in PartitionExecutor.prepareTransaction() if there is a conflict... but I haven't tested it. I think I'm going to walk home now and work on it a bit more until KB comes home. #132
