138422990a - removed useCell option: the indexCell data structure is now the default index structure; old collection data is still migrated
- added some debugging output to balancer to find a bug
- removed unused classes for index collection handling
- changed some default values for the process handling: more memory needed to prevent OOM

67aaffc0a2 - added Latency control to the crawler:
because of the strongly enhanced indexing speed when using the new IndexCell RWI data structures (> 2000PPM on my notebook), it is now necessary to control the crawling speed depending on the response time of the target server (which is also YaCy in case of some intranet indexing use cases).
The latency factor in crawl delay times is derived from the time that a target hosts takes to answer on http requests. For internet domains, the crawl delay is a minimum of twice the response time, in intranet cases the delay time is now a halve of the response time.

- added API to monitor the latency times of the crawler:
a new api at /api/latency_p.xml returns the current response times of domains, the time when the domain was accessed by the crawler the last time and many more attributes.

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.

f6d989aa04 added new class RowSetArray which arranges RowSet objects like Elements in a hashtable, but still provides the functionality of sorted enumeration. The new class is now integrated into the ObjectIndexCache, which is the core class to provide index functions to all database files. The new index access is about twice as fast as before. This has strong speed enhancement effects on all parts of YaCy.
The speed of the kelondro indexing class ObjectIndexCache can be compared with Javas standard TreeMap with the main method in IntegerHandleIndex. The result is, that the kelondro indexing needs only 1/5 of the memory that TreeMap uses! In exchange, the kelondro classes are slower than TreeMap, about four (!) times slower. However, this is not so bad because the better use of the memory is a strong advantage and makes it possible that YaCy can maintain such a large number of document (> 50 million) in one peer.

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.
