|| | Abstract base class to allow "printing" of complex types through
|| | the Print class.
|| |
|| | Wiring Common API
|| #
||
|| @notes
|| | The Printable class provides a way for new classes to allow themselves
|| | to be printed.  By deriving from Printable and implementing the printTo
|| | method, it will then be possible for users to print out instances of this
|| | class by passing them into the usual Print::print and Print::println
|| | methods.
|| #
||
|| @example
|| | class T : public Printable {
|| |   public:
|| |     void printTo(Print &p) {
|| |       p.print("test");
|| |     }
|| | };
