b622884be6 [ckks] API improvements and documentation (#80) 
[ckks/dckks] : API changes:
- RotateColumns -> Rotate
- EvaluateChebySpecial is removed. Now the user needs to do the change of variable before the evaluation.
- Added MultByGaussianInteger/MultByGaussianIntegerAndAdd
- Encoder now takes logSlots instead of slots. This forbids giving zero slots or a non power of two slot number.
- Improved API documentation
- added the RescaleNew method to the ckks.Evaluator interface (closes #83)

f023ff529d [ckks] polynomial evaluation return an error when ciphertext level doesn't enable full evaluation (closes #71) 
In addition to the partially evaluated result, the homomorphic polynomial evaluation methods return an error if the ciphertext level does not enable full evaluation.

6d19e61e0e Fixes 
BFV/CKKS : ciphertext marshaling now properly works when the target is a ciphertext that isnt a bfv or ckks element.

BFV/CKKS : API change on key-generator, Gen is now a prefix to indicate that there is sampling, while New is a prefixe to indicate the creation of an empty struct.
