Proposed changes

This brings a few features into the develop branch

• Removes the need for reactor objects to have a .rotation_angle when making a neutronicsModelFromReactor
• Adds the ability to export wires (as well as solids) to a stp format
• Adds a ShellFS parametric shape which allows a shell to be made
