A Wiring/Arduino library to tokenize and parse commands received over a serial port.

The original version of this library was written by Steven Cogswell (published May 23, 2011 in his blog post "A Minimal Arduino Library for Processing Serial Commands").

This is a heavily modified version with smaller footprint and a cleaned up code by Stefan Rado.

And then modified by Mark Pruden to separate the handing of command from the main serial processing class This allows multi level commands to be handled, since the command handler can have a command which invokes another command handler, e.g. recursive.
