track all constraints and easy to activate/deactivate any one of them.

Example

Setup constraints

[self.redView activateConstraints:^{ self.redView.height_attr.constant = 100; self.redView.width_attr = self.blueView.width_attr; self.redView.top_attr = self.blueView.top_attr; self.redView.leading_attr = self.blueView.trailing_attr;    }];

Alter value of a constraint

self.blueView.width_attr.constant = 100;

Obtain a constraint

NSLayoutConstraint *cons = [self.titleLabel constraintAccordingToAttribute:self.titleLabel.bottom_attr andAttribute:self.subtitleLabel.top_attr];
