Modelica.Blocks.Examples.PID_Controller in MSL 3.1 not balanced

[Peter Aronsson]

Check of Modelica.Blocks.Examples.PID_Controller in MSL 3.1 gives:

"Check of Modelica.Blocks.Examples.PID_Controller completed.
Class Modelica.Blocks.Examples.PID_Controller has 75 equation(s) and 76 variable(s).
40 of these are trivial equation(s).
"

I.e. not balanced.

Closing this as it works in trunk, and was probably fixed previously. I had to add support for ignoring assertions in if-equations so checkModel succeeds (OpenModelica doesn't support it, so we need to ignore it in order to count equations...):
