Detailed Description

This class is essentially used to "save your settings" (chip select, clock rate, SPI mode, etc) when it comes to multi-peripheral projects. It was more useful before all these settings ended up as params in Spi.sendReceive, but it's still nice to use this as a container; SPI peripheral drivers can pass values directly from the constructor to this class's constructor, and never worry about that stuff again.
