===============================
Deduplicate Contacts by website
===============================
This module extends the criteria to match duplicated contacts using the field
website.
Usage
=====
To use this module, you need to:
* Go to *Sales > Tools > Deduplicate Contacts*.
* Mark "Website" in the section "Search duplicates based on duplicated data
in".
* This criteria will be used for deduplicating.
If merging 2 contacts, one with reference, and another without, and being the target
one the contact without reference, the constraint is raised as the reference value
is copied before unlinking the other contact.
We avoid it disabling the constraint when merging.
