AbstractDensity is not generic
The current implementation of AbstractDensity assumes that all parameters are simple float values. While this assumption makes sense and covers most cases, there is no reason why AbstractDensity should not be a generic class that works with parameters
of any type, e.g. a custom Parameter class.
