											This case deals with the way to handle side effects induced while transforming an element. We will start from an imperative algorithm to create a 
											transformation between two metamodels. This algorithm will introduce a side effect problem. After several iteration a solution will be provided
											following ATL philosophy.

												<i>ATL concepts encountered:</i>
												ATL imperative parts for dealing with complex situation, and
												Chain of ATL transformations to divide transformation complexity and to avoid imperative parts.
