## Detailed Description

pfodRingBuffer for Arduino Implements a ring buffer implementation of an Arduino Stream upto 32K buffers NOTE: this implementation DOES NOT BLOCK if the buffer is full extra bytes written are quietly dropped.

markWrite() marks current write position resetWrite() resets buffer to previous markWrite effectively deleting any bytes written between markWrite() and resetWrite() any call to read() or flush() or clear() or resetWrite() clears the markWrite multiple calls to markWrite() only saves the last one.
