Exploded views demo in caps2tacs

[sean-engelstad]

• ability to run main tacs analysis in different caps directories
• switch from loft to rule in caps_wing example
• New script examples/caps_wing/8_make_exploded_views.py shows how to make exploded views of a wing in paraview (see below image). You can set an "exploded" config parameter for instance (although you don't have to do it that way). Then use parallel tacsAIM instances to generate the mesh of each subcomponent of the structure and manipulate them all separately in paraview for instance.
• The second example shows an exploded view of something more complicated that was generated in FUNtoFEM - a supersonic transport wing.
