[Bug] The logic from GaloisElement to Galois Index. #1

It seems current Phantom determines the index of the GaloisKey to used bascially from "order of the given galois elements" within the create_galois_key(). However, the PhantomContext creates the GaloisTool before the GaloisKeys are generated (using some fixed order of galois elements).

I see, we can set the galois_elts in EncryptionParamers orz....

Thanks for highlighting this. We plan to enhance our documentation shortly.
