[igraph] Vertex ID's during deletion

[Nicholas Dahm]

Hi All,

As the C interface isn't stable or expansive, I'm keeping track of attributes 
in my own array. Previously on graph change I would just delete all attributes 
and re-calculate them, but now I want to simply update them instead. However 
this requires keeping track of vertex id's during deletions.

On deletion, do vertex id's simply decrease to fill any gaps, so if I delete 
vertices 4 and 6, old vertex 5 becomes new vertex 4, old vertex 7 becomes new 
vertex 5, old vertex 8 becomes new vertex 6, etc.?

cheers

Nick
