Common subexpression elimination example

Extends from Modelica.Icons.Example (Icon for runnable examples).

Information

This is a very simple example demonstrating common subexpression elimination. The Dymola generated C-code of this model is:

W_[0] = sin(Time+1);
W_[1] = W_[0];

Hence, the sine and addition are evaluated once only, which is more efficient.
