This is done on #1304

[YigitElma]

@unalmis @dpanici There are some duplicate notebooks on dev_guide and notebooks/dev_guide folders. Are there any differences with those? Can you delete the old one and put the most updated one to the dev_guide/notebooks folder?

Also, what is compute_2.ipynb?

[dpanici]

don't neeed to change this one

[dpanici]

Use master for grid.ipynb as well
