Such constraints may formulate specific restrictions to web searches
This is implemented by scraping information for constraints from a web
page during parsing, and storing flags to the pages within the web index.
In this first step, only information for index pages ("index of", directory listings)
are scraped and stored in flags
- added new flag class kelondroBitfield
- added scraper method in condenser
- added bitfield structure for all scrape types (see also condenser)
- added bitfield structure for appearance locations (see RWIEntry)
- added handover protocol for remote search and index distribution
- extended kelondroColumn class to hold bitfield types
- added another search attribute on search page (index.html)
- extended search-filter to enable filtering of non-matching constraints
- set all new database types to be default
- refactoring: moved word hash generation to condenser class

- kelondroFlexTables does always load a RAM cache if it has enough
ram assigned. Othervise it creates a kelondroTree file-index.
If more memory is re-assigned, the file-index is deleted again,
and RAM is used. Beware that assignement of too less RAM forces
creation of file indexes and start-up time may last for hours.

* replaced kelondroTree for NURLs by kelondroFlex
* replaced kelondroTree for EURLs by kelondroFlex
take care, may be very buggy
please finish crawls before updating. crawls will be lost.

* cleaned up code
* added unit test code
* migrated ranking RCI computation to kelondroFlex and kelondroCollectionIndex

* adopted all code to use the declaration form of kelondroRow
* fixed a bug in kelondroRow which caused wrong parsing of encoding type
* the bug caused bad database behaviour in new indexCollection data structure.
because of this bug, all test databases are now already void. A new database is created
* the kelondroFlexTable and indexCollection data structures now store a declaration of the row definition
into a properties file along the database files.

shall replace the current assortment files.
* used the kelondroFlexTable to hold the index of collections
* used kelondroRow definitions to declare all data structures
* fixed several bugs that appeared in kelondroRowSet and kelondroRowCollection during testing
