Changed the order of the polynomial:

3rd degree polynomial instead of 2nd degree polynomial.
The 3rd degree polynomial fits the data points a bit better.
Corrected loop order.

I switched m and n at the for loops that create the pseudo 3d function.
Reset ranges to automatic mode:

The scripts sets the ranges from 0 to 4096. Resetting this values will
avoid confusion at subsequent plotting.
Added a README file and two images.

I will edit the README file online.
Update README.md
Update README.md
Update README.md
Update Tasks.md
Extended the gunplot scripts:

I added two scripts to create graphs.
The file 'sub_styles.plt' is necessary to guaranty that all graphs look
the same.
Small changes to other files.
