+Long Pulse.  When receives an input value different from the previous input value,
+    the output goes to that value and the c code begins a counter.
+    It will remain at that initial input value until the counter finishes.
+    If the input value changes after that time, it will immediately transition.
+    If the input value changes before the counter finishes, it will ignore it until the counter finishes.
+    Threshold defined by model rate (in Hz) and wait time (in seconds).
