Automated Sweeps #31
Description
Right now, only individual cases can be run, one at a time.
It would be good to allow the problem object to contain sweeps of angle of attack, etc., and then, after #30 is complete, the post processing functions/objects could actually include full polar information (and probably want to put in the node/control point geometry in there as well).
Similar to the alpha_sweep function in Xfoil.jl, but instead of having to call separate functions, everything would just be one function call and it could be treated differently based on the number of parameter inputs.
