Simple First Order System - FirstOrder

The Modelica By Example target code is:

model FirstOrder
  Real x;
equation
  der(x) = 1-x;
end FirstOrder;

The exported Modelica code is:

model FirstOrder
  Real x;
equation
  der(x)=1-x;
end FirstOrder;

Note that by having the ConstraintBlock Eq owned by the Block FirstOrder that uses it, the constraint property name eq:Eq can be kept short and sweet, and it does not appear explicitly in the exported Modelica code anyway .
