Possible bug in Kalman Filter C++ implementation

[BogdanovKirill]

Hello,

It seems that we should replace this wrong line:
P = _alpha_sq * ((F * P), F.transpose()) + Q;
by this:
P = _alpha_sq * ((F * P) * F.transpose()) + Q;

See python reference code:
self.P = self._alpha_sq * dot(dot(F, self.P), F.T) + Q
