[**Requires LBTATools**] A sticky function to stick stuff using Swift to other sticky stuff. Padding approached from a web developers perspective.

sticky.swift

// USAGES:

// SQUARE WITH A TOP PADDING OF 20
icon.stick(top: view.topAnchor, padTop: 20, width: 80, height: 80)

// PADDING TOP AND RIGHT
label.stick(top: view.topAnchor, trailing: view.trailingAnchor, padding: [20,20,0,0] )

// PADDING TOP AND BOTTOM = 20, RIGHT AND LEFT = 0
label.stick(top: view.topAnchor, trailing: view.trailingAnchor, padding: [20,0] )

// PADDING 20 ALL AROUND
label.stick(top: view.topAnchor, trailing: view.trailingAnchor, padding: [20] )
