c079b18ee7 - refactoring of IntegerHandleIndex and LongHandleIndex: both classes had been merged into the new HandleMap class, which handles (key<byte[]>,n-byte-long) pairs with arbitraty key and value length. This will be useful to get a memory-enhanced/minimized database table indexing.
- added a analysis method that counts bytes that could be saved in case the new HandleMap can be applied in the most efficient way. Look for the log messages beginning with "HeapReader saturation": in most cases we could save about 30% RAM!
- removed the old FlexTable database structure. It was not used any more.
- removed memory statistics in PerformanceMemory about flex tables and node caches (node caches were used by Tree Tables, which are also not used any more)
- add a stub for a steering of navigation functions. That should help to switch off naviagtion computation in cases where it is not demanded by a client

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

7dff1cba62 removed option to use different primary keys in kelondro tables
this option was never used and there is also no use to set other columns but the first as the primary key. as a result, access methods to the key do not need to compute key positions, and they work faster.

13c666adef performance hack to ObjectIndex put() method:
Java standard classes provide a Map Interface, that has a put() method that returns the object that was replaced by the object that was the argument of the put call. The kelondro ObjectIndex defined a put method in the same way, that means it also returned the previous value of the Entry object before the put call. However, this value was not used by the calling code in the most cases. Omitting a return of the previous value would cause some performance benefit. This change implements a put method that does not return the previous value to reflect the common use. Omitting the return of previous values will cause some benefit in performance. The functionality to get the previous value is still maintained, and provided with a new 'replace' method.

8444357291 added new row interator in kelondro tables files that enumerates rows
without an order by the primary key. The result is a very fast enumeration of the Eco table data structure. Other table data types are not affected.
The new enumerator is used for the url export function that can be accessed from the online interface (Index Administration -> URL References -> Export). This export should now be much faster, if all url database files are from type Eco
The new enumeration is also used at other functions in YaCy, i.e. the initialization of the crawl balancer and the initialization of YaCy News.
