Responsible for converting base Python types to format compatible with underlying

database. For SimpleDB, that means everything needs to be converted to a string

when stored in SimpleDB and from a string when retrieved.
|

To convert a value, pass it to the encode or decode method. The encode method
|

will take a Python native value and convert to DB format. The decode method will
|
|
take a DB format value and convert it to Python native format. To find the appropriate
|

method to call, the generic encode/decode methods will look for the type-specific

method by searching for a method called "encode_<type name>" or "decode_<type name>".
