Shorthand for retaining constraint

[steveriggins]

Is there a better shorthand to save a constraint other than [view als_addConstraints:@{...}][0] and making sure we only pass in enough info for one constraint? I noticed that if you pass in more than one, the order is not defined.

I would like to declare all of my constraints, but hold onto one that I might want to adjust a constant on, etc.
