Saved a checkpoint:
Fairly simple, so should be fine. I made it just one part.

Gave some feedback: Ready to use

Saved a checkpoint:
Changed the coding of "swap rows" so that if no entry is given, it takes the original row again in that place.

Used new "bareMatrices" flag to display the augmented systems as they should be.

Gave some feedback: Needs to be tested

Changed visibility of options so that only options that are possible within given matrix size are visible. Made it possible to leave blanks in the multiplication of rows if they are to stay the same.
