run using scipy numerical gradient

python cli.py
--in_obj=data/bunny.obj
--out_obj=data/optimized_bunny.obj
--energy=hinge
--action=optimize

run using exact gradient

python cli.py
--exact_grad
--in_obj=data/bunny.obj
--out_obj=data/optimized_bunny.obj
--energy=hinge
--action=optimize

debug exact gradient

python cli.py
--in_obj=data/bunny.obj
--energy=hinge
--action=check_gradient
