Implement plotting subpackage

[RobPasMue]

Another important point is the visualization of the different objects inside the datamodel. We should consider using PyVista for this task. Points to be taken into account for this task:

• Implement the plotting subpackage
• Consider the creation of a ScenePlotter or similar (please don't use my name suggestion 😄): users will be able to pass in several objects and plot them all together
• All datamodel objects should implement a plot() function. This function should be defined as abstract in the BaseObject class and implemented downstream in each object
• Create a PyGeometry plotting theme so that we do not use the default PyVista theme
• Add documentation
• Add testing

Please consider the following location for the plotting subpackage:

I would like to address this issue if possible, @RobPasMue.

What do you think about having a "DesignPlotter"? Or "AssemblyPlotter"?

This could be started by implementing the following functionality:

# To be renamed after we agree on its final name
plotter = Plotter(**kwargs)
plotter.show()

Which should render a default scene showing a simple grid in the XY plane with the usual red, green, blue frame in the origin of coordinates. Background scene could be pure white.

I would also make sure that this is fully interactive in our notebooks.

Please go ahead @jorgepiloto! Thank you for taking the lead here =)

Regarding the name, I think we could have two things.

• A SketchPlotter for 2D representation of the sketch conceived (we may not need PyVista for this specifically) - we can talk about it on the side.
• A DesignPlotter for 3D representation of design geometry bodies.

If you want to, I'd focus (after solving #39) on #37 @jorgepiloto, since you already have the PR open and half-way through. The DesignPlotter can wait for a later stage. Right now we should try to focus on the PRIORITY-tagged issues. Thanks in advance! We can rename this issue so that it only targets the SketchPlotter and create another issue for the DesignPlotter.
