tdf#128463: Rewrite NamedRanges.py to make it work when run from UI

This commit:
1. Updated the license header;
2. Added docstrings and notes to help the users to understand the API and code.
3. Make the code to create a new sheet named "data", define named ranges in it,
modify the named range, define another named range, fill values in the cells
related to the named ranges, the calcualte sum of each named range, and also
calculate the difference between the two named ranges. The results are stored
in the sheet named "information".
4. Cell alignment and background color methods are also used in this example.
5. Only show the parent function in the UI.
