-> solves a database storage bug
- Modified inverse() so that it works when no extensions are there

- Passed all code through lint (dev)

	- methods Relation::compose (for EquivRelation, Subsum..Relation, and IncompatRelation)
	- methods Cell::compose

new implementation of Alignment::compose -> Now it works

- rationalized Cell id generation and management
- changed annotation tags for qualified names
- various clean up

- Many small improvements of the AlignementServer
- Complete reengineering of the API for version 3.0

    and BasicCell implementations

- prepared a bit mor multiple cell alignments

	n-ary alignment)
- simplifying the error management

- implementation of new output (UTF-8)
- new cut method
- correction of onto/uri generation

New version featuring:

    * Corrected the problem of putting directly distances into strength ({get/set}Measure{1/2} are now called Strength, new class DistanceAlignment which takes care of converting distances into strength);
    * Implemented effectively SymMeanEvaluator with a dispatch per elements;
    * Added correct 1:1 tags to all implemented OWL alignments
    * Used Object in API: no OWL in the format (all API methods which returned OWL... now returns Objects, dynamic typecheckking of the basic methods: maybe not the best idea)
    * Implemented parameters (align() and eval() take an additionnal Parameters parameter, new Parameters interface and BasicParameters class);
    * Corrected the visitor for the Renderer (now robust to subclassing);
    * Built a renderer for RDF and use it (suppression of the write method in Cell and Alignment, Procalign uses the same code for rendering);
    * Added a StringDistance class providing substring and editstriung distances;
    * Reviewed all catch with a printStackTraces (parser still unsatisfactory);
    * Cleaned-up traces;
    * Provided a full-fledged example illustrated with a paper;
    * Corrected StrucSubsDistNameAlignment;
    * Changed name: Evaluator.evaluate() --> Evaluator.eval();
