Generate color based on the given string

let colorHash = PFColorHash()

// in HSL, Hue ∈ [0, 360), Saturation ∈ [0, 1], Lightness ∈ [0, 1]
colorHash.hsl('Hello World') // [ 225, 0.65, 0.35 ]

// in RGB, R, G, B ∈ [0, 255]
colorHash.rgb('Hello World') // [ 134, 150, 196 ]

// in HEX
colorHash.hex('Hello World') // '#8696c4'

let colorHash = PFColorHash(hash: { (str: String) -> Int64 in
	var hashValue: Int64 = 0
	// Your Hash Function Here
	return hashValue
})

let colorHash = PFColorHash(lightness: [0.35, 0.5, 0.65])

let colorHash = PFColorHash(saturation: [0.35, 0.5, 0.65])

let colorHash = PFColorHash(lightness: [0.35, 0.5, 0.65], saturation: [0.35, 0.5, 0.65])
