**Experimental**
ADG725 is an Arduino class that controls two 16 to 1 multiplexers

Only one of the 16 channels can be connected at the same time.
The channels can be set per multiplexer or together in one call.
ADG725 is an Arduino class that controls two 16 to 1 multiplexers
(or 1 to 16 multiplexer) over a SPI like interface.
The channel selection is disjunct which means that only
one of the 16 channels can be connected (selected) at the same time.
The channels can be set per multiplexer or together (same channel) in one call.
The library also support to set them all off (17th state).
On power-up, all switches are in the OFF state.
On power-up, all switches are in the OFF state, so no channel is selected.
This library can be used e.g. to connect 16 analog devices to
This library can be used e.g. to connect 16 analog devices (potmeters) to
one analog port, or to select between 16 DHT22 sensors.
Not tests with hardware have been done yet, so use with care.
