* Cleanup and feature enhancements for CoPhIR data builder

 * locatorstorageCreator: bug fix (the storage is not deleted after building any more :-) )
 * distdistr: no changes (SVN error)

* Added computation of maximal and average delta-distance of triangleeq-breaking object triplets

* Added equality threshold for reflexivity and symmetry check of the metric function

 * DistanceDistributionRandomPairs - counter of distance distribution but not in stream fashion (instead of FullDistanceDistribution)
 * MIndex building classes modified - mainly comments
 * RemoveDuplicatePivots - minor modifications

* Added metric postulates check utility

* SAPIRMetaObjectDataBuilder - updated documentation and parameter handling
* SAPIRMeteObjectXPathFilter - new class - filters the XML files with the passed XPath expression

 * storage creator for Meta Maps
 * major modification for M-Index bulk loader (MIndexDynamicKeysANndSort) - compatible with current M-Index version
 * MESSIF compatibility fixes

* Switched to the new XMExctractor library that utilizes code from SVN xm-extractor/trunk

* extended SelectPivots (compabile)

* SelectPivots -- support for stdin and stdout (unix-filter behavior)
                         -- support for executing the same selecting more times

 * adding back original MChord tools for data pre-processing (now compatible with messif-newbuckets)
 * adding a tool for pre-calculating distances between data objects and an (M-Index) pivot set	

* DistanceDistribution - print format of distances computed changed
* ComputeDistance - new class - computes distances between specific objects

* Few minor changes

 * minor change in parallel sequential-scan storage class
 * created a tool for building a simple locator-object storage 
 * created two tools for printing pivot-distances and query-pivot distances

* Added a parallelizable sequential scan algorithm
* Added utilities for dumping binary-serialized buckets/storages

* Fixed missing close on the compressed streams of the data builder

 * reorganization of the files to sort and prepare M-Chord recursive data

* Added SortingIterator class providing a generic sort-merging iterator
* Added MChord key-parts builder (rewritten the original CalculateMChordKeys + SortObjectsByKey and uses PartitionMChordData)

 * sorting is now compatible with n-level MChord
 * adding now  respects boundaries ofthe clusters

* MESSIF-compatibility change in sequential scan

* Removed bucket dispatcher (standalone bucket is used now)
* Added finalizer to clean-up the bucket
* Update to delete operation - only one object is deleted now

 * adding support for multi-level MChord to CalculateMChordKeys
 * created a modification of "DistanceDistribution" which takes all pairs from the samle set
