Units in print_results()

[chihchunhsu]

When using print_results(), the default and only unit for inclination (and aop or pan) is radians, maybe the unit degree can be added as a feature. Also the units can be added in the output as well to avoid any confusion. (I am happy to contribute to this).

Sure, sounds like a good idea! Would be wonderful if you'd be willing to make that change. Thanks Dino!

Sounds good! Pull request made; it should be an easy review
