if duplicates, then let user choose which z-value should be kept

[hugoledoux]

• first
• latest
• highest
• lowest
• average is not possible I guess

Could you clarify the context? What duplicates, in what call?

[hugoledoux]

duplicates in x-y so insertion where a vertex already exists.

Right now the first insertion is what stays, but some applications (creation of a DSM eg) would benefit from another behaviour.

It's a new attribute of the Triangulation struct that can be setup with set_duplicates_handling() and there are four choices:

1. First (default)
2. Last
3. Highest
4. Lowest
