[Low] Add a parameter sweep option

[LorenaH84]

As many users will want to do a parameters sweep we should make it easier for them by including this as an option for the most relevant parameters like anode thickness, cathode thickness, C-rate, etc. This issue has the purpose to discuss what this option would contain and how it can be implemented into the GUI.

Wanted features:

1. User can fill in a range of values for a certain parameter.
2. The parameter range is included in the downloadable parameters files.
3. The simulation runs for every value included in the range and the GUI shows the progress.
4. A clear visualization of the results so the user can easily compare for the different values.
5. The user can download the results for every value.

Ideas:
