added indexing of relators and corresponding derivation relations
fixed name prefix for Relator class
Implemented Relator-Derivation tracking mechanism. PLEASE NOTE THAT, as the author, I strongly disagree with this workaround which is kind of "broken by design". Anyway, for the scope of my contribution, I must follow the shortest path ("quick and dirty"", belah!), also because no regression test has been provided by previous authors of the module.
added oled log lock file to .gitignore
changed cardinalitites in the Marriage relator (in a nonsense way, but, still)
first part of the richer Relator verbalization implemented: mediated roles.
second part of the richer Relator verbalization implemented: Relator instances per Role
BUG FIX: relator and roles are named in proper case (not lowercase)
third part of the richer Relator verbalization implemented: derived material relation and involved roles (first DRAFT)
added documentation for FileManager.cardinalityToString(int c) method
improved cardinality representation
