## Usage

Сreate constraints with simple expressions:

```swift

view1.ignoreAutoresizingMask()

view1.centerX =| view2.centerX + 10

view1.centerY =| 15

view1.width <=| 200

view1.width >=| 100

//or

view1.width =| 100...200

view1.height =| view2.height / 2 + 20

...

view.width =| 100

view.width =| 200 //automatically replaces previuos width constraint

...

view1.height.priority(.defaultLow) =| 0

...

view1.height.priority(900) =| 10

...

let constraint: NSLayoutConstraint = view1.height.deactivated =| 200

...

view1.height =| view1.superview

view1.centerX =| view2

...

[view1, view2].ignoreAutoresizingMask()

[view1, view2].height =| 200

view1[.centerX, .centerY] =| 0

view1.edges(.vertical) =| 0

...

Axis.vertical =| [10, view1, 0..., view2.fixed(200), 0...5, view3.centerY, 10]

...

view1.top =| view1.leading //compile error, you cannot combine incompatible attributes

```

Supported operators: `=|`, `<=|`, `>=|`

Every operator returns a `NSLayoutConstraint` instance with the `isActive` property set to `true`.
