YAML mapping documentation of uniqueConstraint

[stollr]

I have provided an example of YAML mapping for unique constraints which is equivalent to the annotation reference for unique constraints.

It is really basic, but I think better than nothing. Because there are severall people who search for that.

See

• http://stackoverflow.com/questions/8893473/how-to-add-a-constraint-index-in-yaml-doctrine-2
• http://stackoverflow.com/questions/7347581/how-to-create-a-unique-constraints-in-yml-in-doctrine2
• http://www.ozonesolutions.com/programming/2011/08/symfony-with-doctrine-multiple-unique-columns/

I felt the need of that doc, too ;)
