* distributed M-Index moved to separate GIT Project
 * modifs due to devel of dm-index

    - ID-object index (to be stored on SSD) is created by two interfaces and a class (package mindex.pppdata)
    - Refinement processor created to refine the candidates within a separate thread

 * minor modifs

 * fixed a BIG BUG in "reorganizeOverfilledBucket" that caused loss of data in case of no sub-index defined and the lowest bucket were overfilled
 * efficiency improvements in PartiallyOrderedCollection
 * much more efficient reading of PPPCOdeObjects from byte[]
 * automatic leaf size in PPPCodeAlg is now calculated so that the resulting capacities are smaller and shrinking with level
 * added richString() in PPPCodeAlgorithm
 * many smaller improvements

 * reading sizes of nodes and data
 

 * added sequential processing of PPP Approx KNN
 * not the whole queue is sorted

 * 

 * setting of QueryPPPDistCal possible via parameter
 * several minor modifications before refactoring (to store only last pivot index in cells in most cases)

* range implemented but SinglePPPCodeDistance calculators

   - to be reworked with the aid of MetricIndex method

 * testing of PPP-Code (NoDataMIndex)

 * a small bug fix in InternalCell
 * added a support for easy location of a cell responsible for given object in a dynamic M-Index

 * preparation for distributed PP calculator

  * one static method moved from MetricIndex to MetricIndexes

 * comments to NoDataProcessor
