Inputs

x,y,z: Earth Centered Earth Fixed (ECEF) coordinates of test point (meters)
lat0, lon0, alt0: ellipsoid geodetic coordinates of observer/reference (degrees, degrees, meters)
spheroid: referenceEllipsoid
angleUnit: string for angular units. Default 'd': degrees

outputs

North,East,Down: coordinates of points (meters)
