What kind of change does this PR introduce?
In the search tree, several network can be incompatible so if one was applied, it is useless to try to apply incompatible remedial actions because they would just override the currently applied remedial action's behaviour.

Two elementary actions are compatible if:

• they have different types (ex: topo and injection)
• they have the same type but different network elements
• they have the same type and the same network elements + the same action type for topo / the same setpoint for injections

A network action NA1 is said to be included in another network action NA2 (NA1⊂NA2) if all the elementary actions of NA1 are elementary actions of NA2.

NA1 and NA2 are equal if all their elementary actions are equal (NA1⊂NA2 and NA2⊂NA1)

Two network actions are compatible if :

• one is not included in the other
• (thus they are different)
• their elementary actions are compatible pairwise

otherwise they are incompatible.

A list of network actions is incompatible if at least two of there network actions are not compatible.
