ENH: Added AbstractModel::IsModified(); Tested IsModified() when closing window/quitting application.

ENH: Managed load vs. import image-models from file(s) in DatasetModel; Parsed loaded DatasetDescriptor in DatasetModel to reload imported images.

ENH: Moved creation of empty XML DOM into DatasetDescriptor::BuildDocument(); Improved ::virtual_BuildModel() to build in-memory XML DOM or to read it from file (if a non-NULL and valid ::BuildContext(filename) argument has been provided); Improved ::Read() method; Added qDebug() messages in ::Read() and ::Write() methods; Moved code into ::BuildDocument() method.

ENH: Moved DatasetDescriptor XML tag names from #define to static constants (reason: need usage in inline methods).

ENH: Moved DatasetDescriptor XML tag names into #define constants; Changed DatasetDescriptor::CreateContainerNode< TContainer >() to ::CreateContainerNode< TInputIterator >() to comply with STL algorithm pattern; Added image ID to DatasetDescriptor::InsertImageModel().

ENH: Added AbstractModel::GetParentModel<>(); Created DatasetDescriptor XML file skeleton; Added interface to store/read image model in DatasetDescriptor.

ENH: Moved generated quicklook image-file into dataset directory; Added DatasetModel::GetDirectory() accessor; Added QuicklookModel::GetImageModel<>() accessors; Added VectorImageModel::GetDatasetModel() accessor; Remove unnecessary typedefs in QuicklookModel.h.

COMP: Added QtXml dependency. ENH: Added DatasetDescriptor ::Read() and ::Write() methods; Written empty DatasetDescriptor when creating empty dataset on disk; Enhanced SystemError (added ::GetErrorCode() method); Fixed I18nAplication::MakeCacheDir().

ENH: Added mvd::ToStdString() and mvd::FromStdString(); Replaced bad conversions by safe To/FromStdString() functions.

ENH: Moved instanciation of DatasetModel from MainWindow::on_action_Open_activated() to Application::LoadDatasetModel(); Parametrized AbstractModel::BuildModel() with generic (void*) context; Created dataset directory when importing image file.

      - widget size are passed as parameter of LoadFile to do this
     * Add a GetImageLargestPossileRegion that compute the largest region
       of the resolution 0
     * Add helper method that compute the best resolution following a zoom
       factor and add the &res paramater to the filename

ENH: Histogram streamed calculation; AbstractModel::BuildModel() and derived-classes; ::ToImageBase() and ::ToImage(); otb::DynamicCast<>(); AbstractModel::newChildModel<>() and ::parentChildModel(); VectorImageModel::m_Image smart-pointer.

ENH: Changed Application/VectorImageModel hierarchy to Application/DatasetModel/VectorImageModel hierarchy.

REFAC: Changed order of includes (ConfigureMonteverdi2.h before Qt before other includes to prevent system compilation problems).

REFAC: Moved i18n part of mvdApplication into mvdI18nApplication base-class for viewer and manager applications.

REFAC: Updated MyClass skeleton file (Qt 'TRANSLATOR: mvd::MyClass' support for C++ namespaces to comply with Qt lupdate translation tool needs).
