minor bugs solved; RecordImpl now implements DataObject; test data added; UML diagrams added; WARNING: evaluate(Record) does not work properly

operation helpers are now internal classes in individual operations; answer mergers (answer builders) are internal classes in answers

the CoreApplication now works; operations constructed using named parameters; execution of operations tested (just fundamentally); printing of operations and answers into JSON tested;

Example of helper class

compilable sourses (with some exclusions). Should work: FieldMap/DataObject, all operations, execution of operations, Algorithm and its basic implementations. On the way: CoreApplication

new operations and their processing work;\n old operations are not deleted yet, the converted ones are marked as Deprecated;\n sequentialScanNew works - see test/messif/algorithm/AlgorithmOperationTest;\n BinarySerializator and DiskStorage work

Cleanup to allow test execution

Operation annotations

Proxy changes: default methods, verification, exposing fieldMap, support for both FieldMap and ModifiableFieldMap
  Processing: chaining
