'CelestialBody' does not have 'getPVCoordinates'
I know CelestialBody HAS getPVCoordinates in JAVA, but I can't use the method.
For example, in Python,
sun = CelestialBodyFactory.getSun()
dir(sun)
then, I got
['class', 'delattr', 'doc', 'eq', 'format', 'ge',
'getattribute', 'gt', 'hash', 'init', 'le', 'lt', 'ne',
'new', 'reduce', 'reduce_ex', 'repr', 'setattr', 'sizeof',
'str', 'subclasshook', 'jobject', 'bodyOrientedFrame', 'boxfn',
'cast*', 'class', 'class*', 'equals', 'gM', 'getBodyOrientedFrame',
'getClass', 'getGM', 'getInertiallyOrientedFrame', 'getName',
'hashCode', 'inertiallyOrientedFrame', 'instance*', 'name', 'notify',
'notifyAll', 'toString', 'wait', 'wrapfn*']
