1. We now keep an association list (based on AVL trees) for storing (predicate-sets)->((predicate-object-pair-sets)->(subject-sets)).
2. Another big effort in unifying the codebase.

* [SC] Renamed most modules for project-wide consistency.
* [IIMB,IOTW,SC] Extracted code that is generic enough to be used for running other experiments too.
* [INODE,SC] Renamed very many predicates and variables.
* [INODE,NEW] Finalized the assertion of intra-inode partitions based on predicate-object pairs.
* [INODE_EXPORT,SC] Many renamings. Adapted to work with the updated INODE module.
* [INODE_UPDATE,SC] Separate module for updating inodes. This is out of sync with the other modules now...
* [IOTW_WEB,EXT] Use the new options that were added to modules IOTW and INODE.
