Public Member Functions
	Encoder ()
bool	getEnabled (int index)
	Checks if an encoder is powered on and receiving events.
int	getEncoderCount ()
	Gets the number of encoder input channels supported by this board.
int	getIndexPosition (int index)
	Gets the position of an encoder the last time an index pulse occured. An index pulse in this context refers to an input from the encoder the pulses high once every revolution.
int	getInputCount ()
	Gets the number of digital input channels supported by this board.
bool	getInputState (int index)
	Reads the current state of a digital input.
int	getPosition (int index)
	Reads the current position of an encoder.
void	setEnabled (int index, bool enabled)
	Set the powered state of an encoder. If an encoder is not enabled, it will not be given power, and events and changes in position will not be captured.
void	setPosition (int index, int position)
	Sets the offset of an encoder such that current position is the specified value.
