Create first component

[FlorisWL]

Create the first of the three gh components: The one that construct the resultant force, the global force diagram and eventually the support reactions.

Inputs:

• ext. forces (index force[int], magnitude[double], rotation[double])
• supports (index support[int], horizontal constraint[bool], vertical constraint[bool], rotation[double])
• Joints [Point3d]

Outputs:

• Support reactions (form) [line]
• External forces (form) [line]
• Resultant (form) [line]
• Support reaction (force) [line]
• External forces (force) [line]
• Resultant (force) [line]
• Other lines global force diagram (force obviously) [line]

Maybe add an extra component that handles the visualization of this output, so there you input most of this output plus stuff like Location global force diagram [Point3d] and Scale global force diagram [double]. Output is geometry to visualize.

Steps:

• [x] make the component
• [x] define the classes and other stuff to structure the data and computations.
• [x] add more functionality (see comment)
• [x] test
• [x] done

Functionality to add:

• [x] Incorporate relevant error messages: (unstable global structure if support reactions in one line; unstable if < 3 support reaction; SU if >3 supports, invalid if force inputs list lengths don't match each other, invalid if support inputs list lengths don't match each other, ...?)
• [x] Make some inputs of the component optional, like rotation of supports.
• [x] Add more outputs that are relevant for the visuals.
• [ ] Anything else?
