#### Random
* Added `random:randn(deviation: double, mean: double): double`, returns normally distributed double, where `deviation` stands for [Standard deviation](https://en.wikipedia.org/wiki/Standard_deviation), and `mean` specifies middle point
#### animator #### animator
* Added `animator.targetRotationAngle(rotationGroup: string): double` * Added `animator.targetRotationAngle(rotationGroup: string): double`
