  ringbuffer.h - fabooh version of the ringbuffer_t c++ template

  Desc: A c++ template class implementing a lock free fixed sized ringbuffer
        with arbitrary types. The push and pop methods implement adding and
        removing items.  The size and capacity methods return the unread
        and max number of items in the buffer.

        This version has been optimized for embedded single core 32 bit
        mcus. It doesn't disable or enable any interrupts. It is safe
