'''
Creates some new cells at the bottom, with some basic statistical analysis.
Assumptions - Comments:
1. Every set of data is organised column by column. For example, in a sheet with temperatures for some days, every day
has a column of temperatures. We also assume some symmetry: Same number of rows for each column
2. The parameter final_row tells us manually where to start the analysis. It indicates the final row used for data,
but it can be anything
3. New function in at the top to import data from csv file (csv_to_sheet). Accompanied with ff.csv file in the directory
4. all the following could be done under the same for-loop because it is ALMOST EXACTLY the same code.
I let them in separate loops for presentation clarity
### LINES in the analysis sub-sheet ###
1. mean
2. std.deviation
3. median
4. variance
5. max
6. sum
7. count
