Reconstructing images properly using Horn Integration techniques. The pear and sphere look solid. TODO: Apply a better image mask.
Migrated data to a data folder, added a compute mask function, tweaked build surface to yield only the masked portion of an image.
Moved files out of the  directory.
Dropped the tilted_pear.jpg
Added spec_surface_reconstruction script
Deleted old .m files.
Stopped normalizing images to get more faithful reconstructions.
