Convert nextnano³ input file to nextnano++

How to use this automatic conversion:

In the menu select Tools ==> Convert nextnano³ input file to nextnano++

When you use the automatic conversion of nextnano³ input file into nextnano++, you will find that it probably does not work completely.

If you save and run the nextnano++ input file that has been converted and that has the suffix _nnp.in, very likely some errors appear indicating which line(s) to change. Then some manual adjustments are needed, but the rough structure should help a lot for the conversion.
