Widget to create a multipass weld

[marscher]

Since weldx-0.6 we have a multi pass welding schema, which enables the user to define a weld consisting of multiple layers, beads, and weldments.

We want to have a widget (group) to plan such a complex task and export it into this very schema.

Desirable features (this is currently a loose collection of ideas, please feel free to update it):

• create complex welding (robot) programs with a simple to use front end.
• create patterns, which can be reused, repeated (e.g. with a weldx MathematicalExpression)
• each pattern can be placed into seam, it could be checked for "clashes" geometrically.
• a pattern could also be a robot program (fragment), which makes sense locally, but can be extended to a global pattern.
• ...

If we have used weldx to create the input for the robot, we could import the measurements later on attached to the definition of the welding task.
