     * should be unique.  The bases can either be user defined, or any of
     * goog.crypt.baseN.BASE_xxx.
     *
     * The number is in human-readable format, most significant digit first, and is
     * a non-negative integer.  Base designators such as $, 0x, d, b or h (at end)
     * will be interpreted as digits, so avoid them.  Leading zeros will be trimmed.
     *
     * Note: for huge bases the result may be inaccurate because of overflowing
     * 64-bit doubles used by JavaScript for integer calculus.  This may happen
     * if the product of the number of digits in the input and output bases comes
     * close to 10^16, which is VERY unlikely (100M digits in each base), but
     * may be possible in the future unicode world.  (Unicode 3.2 has less than 100K
     * characters.  However, it reserves some more, close to 1M.)

     * @param {string} number The number to convert.
     * @param {string} inputBase The numeric base the number is in (all digits).
     * @param {string} outputBase Requested numeric base.
