Add a DebugTo convenience funtion

Browse source 
One might want to write the debug information somewhere other than
Stdout. This patch adss a DebugTo function and method, that accepts
an io.Writer. It changes the original Debug implementation to call
this new function with a default of os.Stdout, which maintains
backward compatibility.
