Element inheritance mechanism

[rcasteran]

Is your feature request related to a problem? Please describe. Add rule mechanism to allow to derive new elements from the created ones

Describe the solution you'd like

• Support the inheritance between elements through the following command:

  <element 1 name> inherits from <element 2 name>

  Inheritance mechanism must ensure that:

• Every modification of element 2 is applied to element 1
• Any modification of element 1 does not affect element 2 and remains at element 1 level
• element 1 must have the same type than element 2 / must be of a sub type of the type of element 2, otherwise inheritance failed

Describe alternatives you've considered None

Question: Since the beginning, only one parent can be set to the child, is this still True ? If i have "E1 inherits from E2" with E2a child of E2, do i have to add E1 as parent too ?

[rcasteran]

In fact decomposition of E1 = { children of E1 } U decomposition of E2
