// BaseEncode (inputInt, base)
// Base encoder by Cory Alder written in 2011.
// Recursively converts any integer number from base 10 to any base up to 64.
// Only tested on bases 64 and 62. Theoretically should work with any base below 64.
// doesn't accept non integer inputs.

// Based on code by Martin Sorich 2009 nov 10 (http://www.briandunning.com/cf/1088)
