// Usage:
// theta = vang([X,Y]);
// theta_phi = vang([X,Y,Z]);
// Description:
// Given a 2D vector, returns the angle in degrees counter-clockwise from X+ on the XY plane.
// Given a 3D vector, returns [THETA,PHI] where THETA is the number of degrees counter-clockwise from X+ on the XY plane, and PHI is the number of degrees up from the X+ axis along the XZ plane.
