d755a8026d - better OOM protection
- better memory allocation for FlexTable indexes
- splitting between static index and dynamic index (only the dynamic part must grow)
- to enable a merge-iteration of new splittet index, a huge number of classes needed to be adopted for new iterator classes
- added new iterator classes that support cloneable iterators
- adopted all iterator classes to implement cloneable itarators

304412a049 first generation of collection index R/W head path optimization
- collections are now hand-over as collection lists to collection index for merge opertations
- collection index lists are separated into 'new' and 'extend' lists
- lists are written separately
- write operations are done into array sets and array indexes. These are now serialized
- write operations into index files are sorted by index;
  that means that a R/W head does not need to go forward
  and backward, only forward
More enhancements are possible

c67d22116e added exists-check based only on RAM index lookup:
- faster double-check during crawling
- less IO

9a85f5abc3 cleanup
- removed 'deleteComplete' flag; this was used especially for WORDS indexes
- shifted methods from plasmaSwitchboard to plasmaWordIndex

109ed0a0bb - cleaned up code; removed methods to write the old data structures
- added an assortment importer. the old database structures can
  be imported with
  java -classpath classes yacy -migrateassortments
- modified wordmigration. The indexes from WORDS are now imported
  to the collection database. The call is
  java -classpath classes yacy -migratewords
  (as it was)

e357599f92 * fixed problem with indexContainer iteration from RAM:
indexContainers from RAM must be cloned explicitely to prevent
  side-effects on stored indexContainer objects in Cache
* changed behaviour of urlReference deletion from indexContainers:
  deletion does not user retrieval of all Elements from the assortments
* added textual configuration of kelondroRow and kelondroColumn definition
* update of kelondroRow usage in yacyNews
* modified kelondroAttrSeq to use modified kelondroColumn parser

417ed5102e redesign of database iterators:
an iteration of key elements in kelondroTree databases is no longer supported.
this is now replaced by an iteration of kelondroRow.Entry objects from the database
Iteration of keys from the database was mostly followed by retrieval of the row
from the database, whcih caused unnecessary database load.
The index selection was also redesigned to use the new row iteration methods.
This affects many funktions, most important is the DHT selection routine which is now much faster.
