Create PSR-0 compatible namespace and add encoding interface/abstract
These classes will be used to make a collection of descendent encoding
scheme classes.
Add class to handle the Base85 encoding scheme.
Included support for btoa, adobe (ASCII85), and RFC 1924 variations.
Move the Base2n class into the psr-0 folder structure
Code Style: Trim whitespace at end of lines

Add support for encoding/decoding with native PHP functions
Improves the counter examples by shiming the core API.

Micro-improve the decoding of case-insensitive chars
Add constants to support common base32 and base64 encoding schemes
Add my author information and update link to my fork
Implement a static class for constructing common encoding schemes
Uses class constants (enum) to identify the differnt types of encoding.
Makes use of built-in PHP encoding functions where supported.
Add base tests
Add constant for Base64 PHP symbol translations.
Fixed error in translated decoding when native functions used.
Add an examples.php file with the examples from README.
Update README with latest information on library structure.
