+ * Class for counting the number of ticks on a digital input channel.
+ * This is a general purpose class for counting repetitive events. It can return the number
+ * of counts, the period of the most recent cycle, and detect when the signal being counted
+ * has stopped by supplying a maximum cycle time.
+ *
+ * All counters will immediately start counting - Reset() them if you need them
+ * to be zeroed before use.
