We should do this at some point (depending on what we agree on in the guidelines), but this is breaking in my opinion. |

Please describe the problem you are trying to solve.
While working on #2087 I realized that the default of the exchange directory of the m2n is the current working directory.
This makes writing integration tests easy, but is in direct conflict with how preCICE is used in practice.
To follow the proposed application case guidelines precice/preeco-orga#6 one always needs to use
<m2n:... exchange-dir=".." />.In the tutorials, every config specifies this.
Describe the solution you propose.
Change the default to
exchange-dir="..".This could be a breaking change. I am not sure if there is anyone using the default though.
Describe alternatives you've considered
Keep the default as the common working directory.
