Extension methods for long to convert from/to Base 62. Useful for shrinking long numbers to small strings for URLs (bit.ly like).

	public static string ToBase62(this long input)
	{
	string baseChars = "0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ";
	string r = string.Empty;
	int targetBase = baseChars.Length;
	do
	{
	r = string.Format("{0}{1}",
	baseChars[(int)(input % targetBase)],
	r);
