Parametric studies #181

For engineering purposes, users should be able to perform parametric studies/sweep.

Proposed UI

Setup

When defining a global parameter, users can tick "Parametric sweep" and provide a list of values instead of a float.
The rest is unchanged.

Data export

Instead of exporting one csv file, PathView will create one csv file per value.

Visualisation

In the results section, users can decide, thanks to UI elements (sliders, menus, dropdown, etc.), to show either certain values or a range of values.

Then for each scope, each signal (here value for example) is duplicated: value-1, value-2, value-3 etc based on what the user chose to display.
