Method for computing all derived parameters based on chosen primitive parameters.

Parameters

cryptoParams	the crypto parameters object to be populated with parameters.
evalAddCount	number of EvalAdds assuming no EvalMult and KeySwitch operations are performed.
evalMultCount	number of EvalMults assuming no EvalAdd and KeySwitch operations are performed.
keySwitchCount	number of KeySwitch operations assuming no EvalAdd and EvalMult operations are performed.
dcrtBits	number of bits in each CRT modulus
n	ring dimension in case the user wants to use a custom ring dimension
