[Erp5-dev] Redefining isMovement on DeliveryLine ?

[Romain Courteaud]

Hi all,

In the current state, we use hasCellContent on DeliveryLine to know if a Line
is a Movement or not.
Sometimes, a Line can have no cell, and not be a movement either (if line is
used to define a range, a cell are not yet created).

That's why I modified the implementation of hasCellContent.
This change can confused people, so, I think we need to had a new method 
(like isMovement) that we must use instead.

What do you think about it ?
