* the MObject which becomes part of the high-level-model:
|
|
* In order actually to use a track within an Sequence, we need to attach a
|
|
* Placement<mobject::session::Track> to the tree-of-tracks of this Sequence.

|
* Thus, we have one global track-identifier (this class here), but maybe
|
|
* several instances (placement of a track-MO) within various Sequences
