See #115 for brief motivation. Closes #115.
Vector3d.theta,Vector3d.phiandVector3d.rattributes.Vector3d.to_polar()method to returntheta,phiandr. The method takes no parameters.Written simple tests, which pass. Coverage remains at 100%.
Todo:
polar()function defined outside ofVector3d, so this could be used elsewhere? If so, where do you think this should be placed?Vector3d.retc. should returnScalarobjects or numpy arrays. I prefer numpy arrays, since I haven't yet understood the use ofScalar.
