* [DEB] Add a PDF file reference to the high-level predicates that are used for running tests. This allows introspection of results without a Web browser and development server (PGC) running.
* [IOTW_TEST,DEB] New modules with a simple test case for IOTW.
1. Besides inodes (p-shares), isubnodes (po-shares) are asserted as well now.

* [IIMB,SC] Simplified the code for running the IIMB experiments.
* [INODE,NEW] Added the assertion of isubnodes for identity sets that share the same predicate-object pairs.
* [INODE,SC] Simplified the representation of ihierarchies: the number of all pairs is not needed.
* [INODE,SC] The assertion of inodes and isubnodes shares most of the code. Several predicates with shared functionality were created for this.
* [INODE_EXPORT,EXT] Changed the way in which precision and percentage are calculated for an inode. This is very different now after the many changes of the past few week (identity sets are used now, but these statistics should still be expressed in terms of pairs).
