c8624903c6 full redesign of index access data model: 
terms (words) are not any more retrieved by their word hash string, but by a byte[] containing the word hash.
this has strong advantages when RWIs are sorted in the ReferenceContainer Cache and compared with the sun.java TreeMap method, which needed getBytes() and new String() transformations before.
Many thousands of such conversions are now omitted every second, which increases the indexing speed by a factor of two.

89ec3acb3e - full abstraction of index content type: the kelondro full text index may now also contain indexes about other content than text, i.e. navigation indexes or reverse linking indexes. 
- during index joins all word positions are maintained: better ranking for word distance possible; exact phrase match can be implemented soundly

c2359f20dd refactoring: better abstraction of reference and metadata prototypes. 
This is a preparation to introduce other index tables as used now only for reverse text indexes. Next application of the reverse index is a citation index.
Moved to version 0.74

96eaecda3e - added migration class to go from index collections to the index cell data structure. 
- added better control over file deletion, because this sometimes fails, especially on windows
