Hi all,

I'm new to CGAL, so apologies in advance if I ask obvious questions.

I'm starting to use LinearCellComplex to model biological epitheliums 
(those are one cell thick sheets of tissues).
I need to attach ids to faces, vertices and edges, as done in 
Polyhedron_Items_with_id :
http://doc.cgal.org/latest/BGL/classCGAL_1_1Polyhedron__items__with__id__3.html

If I understand correctly, this can be done in the definition of 
CellAttributes. What I'm unsure of is how one can access the DartHandle 
of a cell with a given id latter on, and the correct strategy to make 
sure ids are unique and no collision occur.

So my question is: has anybody already coded ids attributes for LCC? If 
not, what do you advise?
Subsidiary question: I understand ids help interface Polyhedron_3 with  
the boost graph library, is this achievable for LCC?

The code base is here: 
https://github.com/CellModels/tyssue/tree/linearcellcomplew.

Thank you for your input,

Best,

Guillaume
