+====== Program Flow ======
+In the following the program flow of some important functions is sketched
+===== Reflectivity =====
+  - Read current state from the graphical user interface and check values.
+  - if "Set optical constants automatically is turned on"
+    - Read .db or .e files of each layer. If no file found display error message.
+    - if magnetization is turned on read .m files of each layer. If no file found display error message.
+  - Fill dielectric tensor with proper values of the diagonal and off-diagonal elements.
+  - Run script ("BeforeCalculation")
+  - Calculate reflectivity
+  - Apply post modifications
+===== Calculation of the error for each dataset =====
+  - Check if fit flag is set, otherwise return
+  - Make a private copy of the dataset
+  - Apply qz-shift, energy-shift, scaling and translation to the datasets energy table and qz table.
+  - Apply post-modifications to the dataset.
+  - Check, which type of dataset this is. This depends on the data in the dataset. The priority is reflectivity > asymmetry > Rp and Rm. Separate datasets if you want to calculate the different curves.
+  - Calculate the corresponding curve for the same datapoints as the measurement. (This is equivalent to the "use dataset points for simulatio"
+  - Calculate Chi^2 between dataset and simulation.
+===== Energy scan =====
+===== Show Delta and Beta Spectra =====
+===== Script Execute =====
