Range<Int> に distance 作って Int に指定範囲で乱数を作成させる extension ref: http://qiita.com/lovee/items/942de12e9edb5ad01f48

	//普通に distanceTo を使うからこの方法やめる
	//extension Range where Element: IntegerType {
	extension Range {

	//普通に distanceTo を使うからこの方法やめる
	//var distance: Element {
	// return self.endIndex - self.startIndex
	//}

	var distance: Element.Distance {
