 ==== Counter ====
+This integer counter increments its internal value when the **Increment()** input method is called. It sends a //void// event indicating that its value has changed, and provides an //integer// property (Value) and thus the **get_Value()** property getter method to retrieve the value of the internal counter.
+Moreover, it has the ability to apply a modulo to the incrementing internal counter. This can be useful to make binary counters (modulo = 2) for example. In this case, when the counter comes back to 0, the Carry event is raised, allowing to cascade the counters when a modulo is used, and create a multi-bit counter for example. The value of the modulo is parametrized by the **Modulo** property.
+  * **Increment()**: input method, incrementing the internal counter value.
+  * **^ValueChanged**: //void// notification of incrementation. Use the **get_Value()** property getter as callback value to complete integer method calls.
+  * **^Carry**: //void// notification of reset of the counter value because of modulo value reaching.
+  * **Reset()**: resets the counter, setting 0 for the internal value and sending the ValueChanged event //(introduced in version 870)//.
