| Modified by jmarantz@google.com to: |
| - Add a static map and an initializer function |
| - add a web-safe variant that uses '-' and '_' in lieu of '+' and '/' |
| - change the 'decode' interface to return false if the input contains |
| characters not in the expected char-set. |
| - removed is_base64 helper function and instead rely on the char_maps. |
| - use a static constant for the padding character '=' |
