TODO:
* test the calculation of new fit goodness parameters. Compare with the results of R maybe or gnuplot (http://gnuplot.sourceforge.net/demo_5.0/fit.html).
* add automatic tests for fitting using NIST data e.g. (http://www.itl.nist.gov/div898/strd/nls/nls_main.shtml).
* test 7e7c0e4dd08b4a15d4ce251e64ca267bb2d9e25e on windows.
* use KSharedConfig instead of KConfig?
* Remove the usage of KDialog, switch to QDialog - DONE (Alexander, Fabian)
* consistenly use the DEBUG macro (Stefan), remove the usage of
```
#ifndef NDEBUG
#include <QDebug>
#endif
```
* restoring of dialog sizes doesn't work. KWindowConfig::saveWindowSize(windowHandle(), conf) and KWindowConfig::restoreWindowSize(windowHandle(), conf) don't seem to do the correct job. Also, https://bugs.kde.org/show_bug.cgi?id=386884.
* check whether https://bugs.kde.org/show_bug.cgi?id=379100 was fixed recently with the proper handling of temporary QByteArrays
* finalize the import of Origin projects - shouldn't be "perfect" maybe for the first release, stable import of data containers and more or less usable import of 2D-plots should be enough
* import of HDF5 fails (Stefan)
* theming on windows, fix the problem with the main menu, have a look at kdevelop (https://git.reviewboard.kde.org/r/127979/)
* check menus with no cantor libs found
* Cantor on windows? (Stefan)
* linking on linux produces "* /usr/lib64/gcc/x86_64-suse-linux/4.8/../../../../x86_64-suse-linux/bin/ld: warning: libhdf5.so.10, needed by /usr/lib64/gcc/x86_64-suse-linux/4.8/../../../../lib64/libnetcdf.so, may conflict with libhdf5.so.100". Is linking to libnetcdf.so only maybe enough?
* Mac port improvements
DONE:
* Remove the usage of KDialog, switch to QDialog (Alexander, Fabian)
