16 |   timer.fire()
17 |   
18 |   // LiveLabel Usage 
19 |   liveLabel.fromColor = UIColor.init(netHex: 0x00C9FF).cgColor // Here is an entension init method for UIColor from LiveLabel.swift
20 |   liveLabel.toColor = UIColor.init(netHex: 0x92FE9D).cgColor // Here is an entension init method for UIColor from LiveLabel.swift
21 |   liveLabel.setAnimationEnabled(true)
22 |   ...
