The numerical integration of data sets was fixed and the possibility to integrate analytical functions was added. 2D numerical integration for matrices was added. The matrix undo/redo framework was improved and all possible memory overflows when working with matrices were fixed. The custom actions dialog was improved. A few minor bugs were fixed.
