5e31bad711 - the webgraph shall store all links which appear on a web page and not
all unique links! This made it necessary, that a large portion of the
parser and link processing classes must be adopted to carry a different
type of link collection which carry a property attribute which are
attached to web anchors.
- introduction of a new URL class, AnchorURL
- the other url classes, DigestURI and MultiProtocolURI had been renamed
and refactored to fit into a new document package schema, document.id
- cleanup of net.yacy.cora.document package and refactoring

ada3f27de7 added three new field for a better ranking: references_internal_i,
references_external_i and references_exthosts_i. These can be used to
count and evaluate the number of external links to every web page. An
experimental ranking function can be i.e.:
div(add(references_internal_i,product(references_external_i,references_exthosts_i)),add(clickdepth_i,1))

10da7335ea performance hack: use a hash cache for all hashes that are computed by a
byte array. If this hash is used in a HashMap (which is very often the
case) then this hack eliminates a lot of re-computations of the same
hash.

4bea3f9714 hack to reduce resource contention caused by massive UTF8 decodings which use java.nio resources:
used a ASCII String <-> byte[] conversion wherever possible. Many Strings in YaCy are hashes which are pure ASCII (base64 hashes).
The new ASCII String <-> byte[] conversion method have less computation overhead than the UTF8 conversion.

123375bfba added a new yacy protocol servlet 'idx'. This returns an index to one of the data entities that is stored in YaCy.
This servlet currently only serves for indexes to the web structure hosts. It can be tested by calling
http://localhost:8090/yacy/idx.json?object=host
This yacy protocol servlet is the first one that returns JSON code and that also shows index entries in a readable format. This will make the development of API applications much easier. This is also an example implementation for possible json versions of the other existing YaCy protocol interfaces.

The main purpose of this new feature is to provide a distributed block rank collection feature. Creating a block rank is very difficult if the forward-link data is first collected and then one peer must create a backward-link index. This interface provides already a partial backward index and therefore a collection of all these indexes needs only to be joined which is very easy. The result should be the computation of new block rank tables that all peers can perform.

To reduce load from peers this servlet buffers all data and refreshes it only once in 12 hours. This very slow update cycle is needed because the interface will be called round-robin from all peers once after start-up.

1a8a134e0c continuing String-hash - to - byte[]-hash redesign that was started in SVN 6775 and continued in SVN 6790
The result should be a less usage of new String() and less memory usage (since a String-encapsulated byte[] has 40 bytes overhead)

4df88a4e7a - fixes for missing or bad hashCode computation
- fixes for bad equals() methods that had not been used by hash maps and therefore some classes did not work as objects in hash maps.
- this may also affect some cases where double-checks should have been, but did not work.
