==Usage==

var hexToRgba = require("hex-to-rgba");

hexToRgba('112233', '0.5'); // "rgba(17, 34, 51, 0.5)"
hexToRgba('#112233', 0.75); // "rgba(17, 34, 51, 0.75)"
hexToRgba('#123', 0.2) // "rgba(17, 34, 51, 0.2)"
hexToRgba('112233'); // "rgb(17, 34, 51)"
hexToRgba('123'); // "rgb(17, 34, 51)"
hexToRgba('#123'); // "rgb(17, 34, 51)"

==Parameters== hex: The hex value to convert. ('123456'. '#123456', ''123', '#123') a: An alpha value to apply. (optional) ('0.5', 0.25)

==Returns== An rgb or rgba value. ('rgb(11, 22, 33)', 'rgba(11, 22, 33, 0.5)')
