Classes
`ZestyParser`	Parses one stream of data, by means of `tokens`.

Exceptions
`NotMatched`	Raised by a token if it has failed to match at the parser's current cursor.
`ParseError`	Raised by a token to indicate that a parse error has occurred.

Function Summary
	`CallbackFor(token)` Function decorator indicating that the function should be set as the callback of the given token; returns the token instead of the function.
	`DebugNote(note)` Factory which creates a logging function usable as a token callback.

Function Details

CallbackFor(token)

Function decorator indicating that the function should be set as the callback of the given token; returns the token instead of the function.

Example:

       @CallbackFor(Token('([0-9]+)'))
       def T_INT(r):
               print r

This is equivalent to:

       def T_INT(r):
               print r
       T_INT = Token('([0-9]+)', callback=T_INT)

DebugNote(note)

Factory which creates a logging function usable as a token callback. The logging function prints note, the parser's coordinates, and the value matched. It then returns the value unmodified.

Example:

       T_FOO = TokenSeries(RawToken('foo')) >> DebugNote('foo_series')
