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.

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

- after a index selection is made, the index is splitted into its vertical components
- from differrent index selctions the splitted components can be accumulated before they are placed into the transmission queue
- each splitted chunk gets its own transmission thread
- multiple transmission threads are started concurrently
- the process can be monitored with the blocking queue servlet
To implement that, a new package de.anomic.yacy.dht was created. Some old files have been removed.
The new index distribution model using a vertical DHT was implemented. An abstraction of this model
is implemented in the new dht package as interface. The freeworld network has now a configuration
of two vertial partitions; sixteen partitions are planned and will be configured if the process is bug-free.
This modification has three main targets:
- enhance the DHT transmission speed
- with a vertical DHT, a search will speed up. With two partitions, two times. With sixteen, sixteen times.
- the vertical DHT will apply a semi-dht for URLs, and peers will receive a fraction of the overall URLs they received before.
with two partitions, the fractions will be halve. With sixteen partitions, a 1/16 of the previous number of URLs.
BE CAREFULL, THIS IS A MAJOR CODE CHANGE, POSSIBLY FULL OF BUGS AND HARMFUL THINGS.

- implemented vertical DHT acceptance ("my own DHT") to accept new targets
- added new target computation for global search: addresses vertical targets also
- enhanced remote crawling: collection of remote crawl urls if queue has less than 100 entries (was: 0 entries)
- better performance value computations for PPM selection in network configuration

- two different computations (but mathematical equivalent) of the DHT distance had been consolidated
- moved from 0.0 .. 1.0 double-range position computation to 0 .. Long.Max range for DHT targets
- added fast Long - to - hash computation
- high-precision target computation of gaps for new peers
- added new target computation for horizontal and vertical DHT targets (not yet in use)

- moved constants from plasmaSwitchboard to own class (all 232 ;)
- moved remoteProxy-Methods to httpRemoteProxyConfig, better names
- removed some unnecessary code (else-statements)

This change is inspired by the need to see a network connected to the index it creates in a indexing team.
It is not possible to divide the network and the index. Therefore all control files for the network was moved to the network within the INDEX/<network-name> subfolder.
The remaining YACYDB is superfluous and can be deleted.
The yacyDB and yacyNews data structures are now part of plasmaWordIndex. Therefore all methods, using static access to yacySeedDB had to be rewritten. A special problem had been all the port forwarding methods which had been tightly mixed with seed construction. It was not possible to move the port forwarding functions to the place, meaning and usage of plasmaWordIndex. Therefore the port forwarding had been deleted (I guess nobody used it and it can be simulated by methods outside of YaCy).
The mySeed.txt is automatically moved to the current network position. A new effect causes that every network will create a different local seed file, which is ok, since the seed identifies the peer only against the network (it is the purpose of the seed hash to give a peer a location within the DHT).
No other functional change has been made. The next steps to enable network switcing are:
- shift of crawler tables from PLASMADB into the network (crawls are also network-specific)
- possibly shift of plasmaWordIndex code into yacy package (index management is network-specific)
- servlet to switch networks

and replaced old fist hash computation by new method that tries to find a gap in the current dht
to do this, it is necessary that the network bootstraping is done before the own hash is computed
this made further redesigns in peer initialization order necessary

- the network configuration page shows a new option: robinson clusters
- when a global search is made, all robinson peers are excluded, but:
- robinson peers/clusters that provide peer tags and where search words match
such tags, they are included in global search. Therefore, robinson peers/clusters
support the global yacy network with their indexes, without doin DHT-exchange

the field contains now a time in UDC-0 (instead relative to local UDC offset)
this fixes a bug in peer selection, where an iteration over all seeds
ordered by lastseen did not work correctly.
Problems may occur because the new meaning of this field may mix with
the different meaning of that field in older peers

the kelondro database needs specific information about the order of
base64-encoded keys. Since no other package depends on base64
(only the httpd uses base64 for encryption, but does not need to encode these strings)
it is good to move base64 encoding to the new ordering classes in kelondro.
