New functions were added for Fourier transformations and a direct search solver. A "columns fit" button was added in the matrix and presentation viewer. A function viewer, high low charts, a plugins dialog, a search bar for the trees, and a menu to move items in a tree were added. A big part of the project is now covered by unit testing. GUI unit testing was added with SWTBot. The code was tested with Findbugs. ISQLLib is now a separated library. The class loader is based on configuration files.
