Reformulated the assert statement that checks for the correct value of <code>densitySelection</code>.
Added uses(Modelica_StateGraph2(version=2.0.1)) declaration as this is used by some models.
Added each attribute to arrays and added experiment annotation.
Changed media to use Buildings.Media.Interfaces.Choices.IndependentVariables instead of the declaration in the MSL, as this class moved between 3.2 and 3.2.1
