##Usage
import CryptoSwift
/* Calculate hash for array of bytes */
var data:NSData = NSData(bytes: [49, 50, 51] as [Byte], length: 3)
if let data = CryptoHash.md5.hash(data) {
println(data.hexString)
}
/* Calculate hash for string with convenience extension */
var string:String = "123"
if let hash = string.md5() {
println(string.md5())
}
