+/**
+ * Class for Spike style relay outputs.
+ * Relays are intended to be connected to spikes or similar relays. The relay channels controls
+ * a pair of pins that are either both off, one on, the other on, or both on. This translates into
+ * two spike outputs at 0v, one at 12v and one at 0v, one at 0v and the other at 12v, or two
+ * spike outputs at 12V. This allows off, full forward, or full reverse control of motors without
+ * variable speed. It also allows the two channels (forward and reverse) to be used independently
+ * for something that does not care about voltage polatiry (like a solenoid).
