this is in line with the mail i sent to merlin google groups, to extend the falcon entities to have merlin entities. I have added a sample function to ProcessMerlin to display the usage. 
For feed we have we have methods ready like to Feed.generateData, Feed.createEmptyFolders, Feed.addCluster etc..... will send them shortly . 
Can send now also but lot of conflicts already as others request r merged over it.
