 - Once you have refactored the code, try calling the `solve()` function again through a Python script or directly in a Python shell. Compare the plots with the plots in the figure you saved earlier. Both outputs should be identical.
 - The function `solve()` should take in physical parameters as input arguments. In this case, change the parameters `dx`, `dy` and `D` such that they are passed to the `solve()` function by the user. Provide default values for all three of these parameters.
-- In some cases an additional `__init__.py` file may be necessary on each level of the directory structure to ensure that the local import `from .output ...` works. First try to run the refactored code without adding any additional file, and if it is does not work, add the `__init__.py` file. The `__init__.py` should be empty in this case. An explanation of why this file is necessary is found in the [Python packaging documentation](https://packaging.python.org/en/latest/tutorials/packaging-projects/#a-simple-project).
 
 ## Step 3 - Creating folder structure for packaging

 - **Note**: General recommendation is to have the name of the folder having the source files to be same as the name of the package as seen when imported at the time of use.
 - The `README.md` file consists of a longer description about the code and what it does. Take the information about the code from Step 1 of this exercise and add it to the README. In addition to this fill out the empty sections of the README with relevant information.
 - In the `pyproject.toml`, name your package `<your-GitLab-username>_diffusion2d` (the underscore `_` between your GitLab username and diffusion2d is important, because any other symbol will not work). We will use semantic versioning, so the version you are developing will be `0.0.1`. The package url is the url of the GitHub repository of this exercise code.
-- As the package should be easy to install and provide maximum possible information, try to include as many configuration options as possible.
